Olof Johansson 874767e52c Just a single wkup_m3_ipc clean-up for v4.11 merge window.
We don't currently have anything else for drivers/soc to
 merge, but I'd expect that to change as soon as we can start
 moving PM code into drivers with the recently posted SRAM
 changes. Anyways, sent as a separate pull request to make
 it easy to group the ARM SoC pull requests.

Heiko Stuebner 4c58063d42 soc: rockchip: add driver handling grf setup
The General Register Files are an area of registers containing a lot
of single-bit settings for numerous components as well full components
like usbphy control. Therefore all used components are accessed
via the syscon provided by the grf nodes or from the sub-devices
created through the simple-mfd created from the grf node.

Some settings are not used by anything but will need to be set up
according to expectations on the kernel side.

Best example is the force_jtag setting, which defaults to on and
results in the soc switching the pin-outputs between jtag and sdmmc
automatically depending on the card-detect status. This conflicts
heavily with how the dw_mmc driver expects to do its work and also
with the clock-controller, which has most likely deactivated the
jtag clock due to it being unused.

So far the handling of this setting was living in the mach-rockchip
code for the arm32-based rk3288 but that of course doesn't work
for arm64 socs and would also look ugly for further arm32 socs.

Also always disabling this setting is quite specific to linux and
its subsystems, other operating systems might prefer other settings,
so that the bootloader cannot really set a sane default for all.

So introduce a top-level driver for the grf that handles these
settings that need to be a certain way but nobody cares about.

Other needed settings might surface in the future and can then
be added here, but only as a last option. Ideally general GRF
settings should be handled in the driver needing them.

Highlights include:
 
  - Support for the kexec_file_load() syscall, which is a prereq for secure and
    trusted boot.
 
  - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
 
  - Sort the exception tables at build time, to save time at boot, and store
    them as relative offsets to save space in the kernel image & memory.
 
  - Allow building the kernel with thin archives, which should allow us to build
    an allyesconfig once some other fixes land.
 
  - Build fixes to allow us to correctly rebuild when changing the kernel endian
    from big to little or vice versa.
 
  - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
 
  - Initial stack protector support (-fstack-protector).
 
  - Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
 
  - Fix an oops in cxl coredump generation when cxl_get_fd() is used.
 
  - Freescale updates from Scott: "Highlights include 8xx hugepage support,
    qbman fixes/cleanup, device tree updates, and some misc cleanup."
 
  - Many and varied fixes and minor enhancements as always.

Linus Torvalds 991688bfc6 ARM: SoC driver updates for v4.10
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting

Linus Torvalds 3ec5e8d82b ARM: SoC non-urgent fixes for v4.10
As usual, we queue up a few fixes that don't seem urgent enough to go in
 through -rc, or that just came a little too late given their size.
 
 The zx fixes make the platform finally boot on real hardware, the
 davinci and imx31 get the DT support working better for some of
 the machines that are still normally used with classic board files.
 One tegra fix is important for new bootloader versions, but the
 bug has been around for a while without anyone noticing.
 
 The other changes are mostly cosmetic.

Linus Torvalds b8d2798f32 This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)
  - i.MX imx6ull
  - Socionext's UniPhier SoC CPUs
  - Mediatek MT2701 SoCs
  - Rockchip rk1108 SoCs
  - Qualcomm MSM8994/MSM8992 SoCS
  - Qualcomm RPM Clocks
  - Hisilicon Hi3516CV300 and Hi3798CV200 CRG
  - Oxford Semiconductor OX820 and OX810SE SoCs
  - Renesas RZ/G1M and RZ/GIE SoCs
  - Renesas R-Car RST driver for mode pin states
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver
  - Rockchip rk3399,rk3066 PLL optimizations
  - i.MX LVDS display glitch fixes and AV PLL precision improvements
  - Qualcomm MSM8996 GPU GDSCs, hw controlled GDSCs, and Alpha PLL support
  - Explicit demodularization of always builtin drivers
  - Freescale Qoriq ls1012a and ls1046a support
  - Exynos 5433 parent typo fix and critical clock tagging

  - Fix 4K native sector check
  - Don't power off the card when starting the host
  - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
  - Improve error handling and drop meaningless BUG_ONs()
  - Lots of clean-ups and changes to improve the quality of the code
 
 MMC host:
  - sdhci: Fix tuning sequence and clean-up the related code
  - sdhci: Add support to via DT override broken SDHCI cap register bits
  - sdhci-cadence: Add new driver for Cadence SD4HC SDHCI variant

 As a part of the mmc changes this time, I have also pulled in an immutable
 branch/tag (soc-device-match-tag1) hosted by Geert Uytterhoeven, to share the
 implementation of the new soc_device_match() interface. This is needed by the
 below mmc related changes:
  - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
  - soc: fsl: add GUTS driver for QorIQ platforms

Sudeep Holla 34c1c21e94 soc: fsl: fix section mismatch build warnings
We get the following warning with the driver is compiled in:

WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'

With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported:

WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the
function fsl_guts_probe() to the function
.init.text:of_flat_dt_get_machine_name()
The function fsl_guts_probe() references
the function __init of_flat_dt_get_machine_name().
This is often because fsl_guts_probe lacks a __init
annotation or the annotation of of_flat_dt_get_machine_name is wrong.

This patch fixes the issue by using the normal DT/OF API rather than
the of_flat_* one.

Identification is done using the Product Register or Common Chip Code

fallback if missing.

Jon Hunter 27b12b4e58 soc/tegra: pmc: Simplify IO rail bit handling
The function tegra_io_rail_prepare() converts the IO rail ID into a
bit position that is used to check the status and control the IO rail
in the PMC registers. However, rather than converting to a bit position
it is more useful to convert to a bit-mask because this is what is
actually used. By doing so the BIT() marco only needs to be used once
and we can use the IO_DPD_REQ_CODE_MASK when checking for erroneous rail
IDs.

It is possible for the public functions, tegra_io_rail_power_on/off()
to be called before the PMC device has been probed. If this happens
then the pmc->clk member will not be initialised and the call to
clk_get_rate() in tegra_io_rail_prepare() will return zero and lead
to a divide-by-zero exception. The function clk_get_rate() will return
zero if a NULl clk pointer is passed. Therefore, rather that checking
if pmc->clk is initialised, fix this by checking the return value for
clk_get_rate() to make sure it is not zero.

Laxman Dewangan 21b4991051 soc/tegra: pmc: Add I/O pad voltage support
I/O pins on Tegra SoCs are grouped into so-called I/O pads. Each such
pad can be used to control the common voltage signal level and power
state of the pins in the given pad.

I/O pads can be powered down even if the system is active, which can
save power from that I/O interface. For SoC generations prior to
Tegra124 the I/O pad voltage is automatically detected and hence the
system software doesn't need to configure it. However, starting with
Tegra210 the detection logic has been removed, so explicit control of
the I/O pad voltage by system software is required.

deactivation of unused domains (and probably later genpd accesses as

Add a driver for the Renesas R-Car Gen1 RESET/WDT and R-Car Gen2/Gen3
and RZ/G RST module.

For now this driver just provides an API to obtain the state of the mode
pins, as latched at reset time.  As this is typically called from the
probe function of a clock driver, which can run much earlier than any
initcall, calling rcar_rst_read_mode_pins() just forces an early
initialization of the driver.

Despite the current simple and almost identical handling for all
supported SoCs, the driver matches against SoC-specific compatible
values, as the features provided by the hardware module differ a lot
across the various SoC families and members.

Douglas Anderson 3f2fe461c7 soc: rockchip: power-domain: Don't (incorrectly) set rk3399 up/down counts
On rk3288 it was important that powerdown and powerup counts for the
CPU/GPU in the kernel because:
* The power on default was crazy long.
* We couldn't rely on the firmware to set this up because really this
  wasn't the firmware's job--the kernel was the only one that really
  cared about bringing up / down CPUs and the GPU and doing suspend /
  resume (which involves bringing up / down CPUs).

On newer ARM systems (like rk3399) ARM Trusted Firmware is in charge of
bringing up and down the CPUs and it really should be in charge of
setting all these counts right.  After all ATF is in charge of suspend /
resume and CPU up / down.  Let's get out of the way and let ATF do its
job.

A few other motivations for doing this:
* Depending on another configuration (PMU_24M_EN_CFG) these counts can
  be either in 24M or 32k cycles.  Thus, though ATF isn't really so
  involved in bringing up the GPU, ATF should probably manage the counts
  for everything so it can also manage the 24M / 32k choice.
* It turns out that (right now) 24M mode is broken on rk3399 and not
  being used.  That means that the count the kernel was programming
  in (24) was not 1 us (which it seems was intended) but was actually
  .75 ms
* On rk3399 there are actually 2 separate registers for setting CPU
  up/down time plus 1 register for GPU up/down time.  The curent kernel
  code actually was putting the register for the "little" cores in the
  "CPU" slot and the register for the "big" cores in the "GPU" slot.  It
  was never initting the GPU counts.

Note: this change assumes that ATF will actually set these values at
boot, as I'm proposing in <http://crosreview.com/372381>.

Christophe Leroy 4d486e0083 soc/fsl/qe: fix Oops on CPM1 (and likely CPM2)
Commit 0e6e01ff69 ("CPM/QE: use genalloc to manage CPM/QE muram")
has changed the way muram is managed.
genalloc uses kmalloc(), hence requires the SLAB to be up and running.

On powerpc 8xx, cpm_reset() is called early during startup.
cpm_reset() then calls cpm_muram_init() before SLAB is available,
hence the following Oops.

cpm_reset() cannot be called during initcalls because the CPM is
needed for console.

This patch removes the call to cpm_muram_init() from cpm_reset().
cpm_muram_init() will be called from a new function called cpm_init()
which is declared as subsys_initcall, unless cpm_muram_alloc() is
called earlier for the serial console in which case cpm_muram_init()
will be called from there.

The reason for calling it from two places is that some drivers
(e.g. i2c-cpm) need some of the initialisations done by
cpm_muram_init() but don't call cpm_muram_alloc(). The console
driver calls cpm_muram_alloc() but some platforms might not use
the CPM serial ports for console.

Arnd Bergmann 18a9927878 ARM: ux500: move soc_id driver to drivers/soc
As the ux500 id code is basically a standalone driver, we can move it
out of the arch code into drivers/soc/ux500.

This is a user-visible change, as it moves all the devices in sysfs
from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a
separate device.

Originally the idea was to put all on-chip devices under the soc node,
and ux500 was the first platform to have this device, but later platforms
almost all didn't follow that pattern, so this makes the platform do
the same thing as everyone else.

Since the platform is really obsolete now, I am optimistic that nothing
will break after moving the devices around.

As the SoC driver no longer has access to the private header files,
I'm changing the code to instead look up the address of the backupram
from devicetree, which is a good idea anyway.

Finally, having a separate Kconfig symbol means the driver is now
optional and could even be a loadable module rather than always being
built-in if we allowed that for soc_device.

The Tegra XHCI driver does not currently manage the Tegra XUSB power
partitions and so it these partitions have not been enabled by the
bootloader then the system will crash when probing the XHCI device.

While proper support for managing the power partitions is being

partitions for USB host and super-speed on boot if the XHCI driver is
enabled.

Jon Hunter e2d1796053 soc/tegra: pmc: Initialise power partitions early
If CONFIG_PM_GENERIC_DOMAINS is not enabled, then power partitions
associated with a device will not be enabled automatically by the PM
core when the device is in use. To avoid situations where a device in
a power partition is to be used but the partition is not enabled,
initialise the power partitions for Tegra early in the boot process and
if CONFIG_PM_GENERIC_DOMAINS is not enabled, then power on all
partitions defined in the device-tree blob.

Note that if CONFIG_PM_GENERIC_DOMAINS is not enabled, after the
partitions are turned on, the clocks and resets used as part of the
sequence for turning on the partition are released again as they are no
longer needed by the PMC driver. Another benefit of this is that this
avoids any issues of sharing resets between the PMC driver and other
device drivers that may wish to independently control a particular
reset.

Jon Hunter a83f1fc3f3 soc/tegra: pmc: Don't probe PMC if early initialisation fails
Commit 0259f522e0 ('soc/tegra: pmc: Restore base address on probe
failure') fixes an issue where the PMC base address pointer is not
restored on probe failure. However, this fix creates another problem
where if early initialisation of the PMC driver fails and an initial
mapping for the PMC address space is not created, then when the PMC
device is probed, the PMC base address pointer will not be valid and
this will cause a crash when tegra_pmc_init() is called and attempts
to access a register.

Although the PMC address space is mapped a 2nd time during the probe
and so this could be fixed by populating the base address pointer
earlier during the probe, this adds more complexity to the code.
Moreover, the PMC probe also assumes the the soc data pointer is also
initialised when the device is probed and if not will also lead to a
crash when calling tegra_pmc_init_tsense_reset(). Given that if the
early initialisation does fail then something bad has happen, it seems
acceptable to allow the PMC device probe to fail as well. Therefore, if
the PMC base address pointer or soc data pointer are not valid when
probing the PMC device, WARN and return an error.

The mutex used by the PMC driver may not be initialised if early

Jon Hunter 718a2426e8 soc/tegra: pmc: Don't populate SoC data until register space is mapped
The public functions exported by the PMC driver use the presence of the
SoC data pointer to determine if the PMC device is configured and the
registers can be accessed. However, the SoC data is populated before the
PMC register space is mapped and this opens a window where the SoC data
pointer is valid but the register space has not yet been mapped which
could lead to a crash. Furthermore, if the mapping of the PMC register
space fails, then the SoC data pointer is not cleared and so would
expose a larger window where a crash could occur.

Fix this by initialising the SoC data pointer after the PMC register
space has been mapped.

Jon Hunter 11131895cd soc/tegra: pmc: Fix early initialisation of PMC
During early initialisation, the available power partitions for a given
device is configured as well as the polarity of the PMC interrupt. Both
of which should only be configured if there is a valid device node for
the PMC device. This is because the soc data used for configuring the
power partitions is only available if a device node for the PMC is found
and the code to configure the interrupt polarity uses the device node
pointer directly.

Some early device-tree images may not have this device node and so fix
this by ensuring the device node pointer is valid when configuring these
items.

Jon Hunter 05cfb988a4 soc/tegra: pmc: Initialise resets associated with a power partition
When registering the Tegra power partitions with the generic PM domain
framework, the current state of the each partition is checked and used
as the default state for the partition. However, the state of each reset
associated with the partition is not initialised and so it is possible
that the state of the resets are not in the expected state. For example,
if a partition is on, then the resets should be de-asserted and if the
partition is off, the resets should be asserted.

There have been cases where the bootloader has powered on a partition
and only de-asserted some of the resets to some of the devices in the
partition. This can cause accesses to these devices to hang the system
when the kernel boots and attempts to probe these devices.

Ideally, the driver for the device should ensure the reset has been
de-asserted when probing, but the resets cannot be shared between the
PMC driver (that needs to de-assert/assert the reset when turning the
partition on or off) and another driver because we cannot ensure the
reset is in the correct state.

To ensure the resets are in the correct state, when using the generic
PM domain framework, put each reset associated with the partition in
the correct state (based upon the partition's current state) when
obtaining the resets for a partition.

Geert Uytterhoeven 053239987f soc: renesas: rcar-sysc: Move SYSC interrupt config to rcar-sysc driver
On R-Car H1 and Gen2, the SYSC interrupt registers are always configured
using hardcoded values in platform code. For R-Car Gen2, values are
provided for H2 and M2-W only, other SoCs are not yet supported, and
never will be.

Move this configuration from SoC-specific platform code to the
rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured
from DT. This would be the case not only for H1, H2, and M2-W using a
modern DTS, but also for other R-Car Gen2 SoCs not supported by the
platform code, relying purely on DT.

There is no longer a need to return the mapped register block, hence
make the function return void.

Krzysztof Kozlowski c028e17571 soc: samsung: pm_domains: Prepare for supporting ARMv8 Exynos
The ARMv8 Exynos family (Exynos5433 and Exynos7420) uses different value
(0xf instead of 0x7) for controlling the power domain on/off registers
(both for control and for status).

Choose the value depending on the compatible. This prepares the driver
for supporting ARMv8 SoCs.

Arnd Bergmann 7f058c0a4a soc: mtk-pmic-wrap: avoid integer overflow warning
On ARM64, the mtk-pmic-wrap driver causes a harmless warning:

mtk-pmic-wrap.c:1062:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1074:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
  .int_en_all = ~(BIT(31) | BIT(1)),

The problem is that the result of the BIT() macro is an 'unsigned long',
so taking the bitwise NOT operation of that results in an integer
with the upper 32 bits all set and that cannot be assigned to a
'u32' variable without loss of information.

This is harmless because we were never interested in the upper bits
here anyway, so we can shut up the warning by adding a simple cast
to 'u32'.

Linus Torvalds 4a5219edcd ARM: SoC driver updates for v4.7
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons. For the most part, this is now related to power management
 controllers, which have not yet been abstracted into a separate
 subsystem, and typically require some code in drivers/soc or arch/arm
 to control the power domains.
 
 Another large chunk here is a rework of the NVIDIA Tegra USB3.0
 support, which was surprisingly tricky and took a long time to
 get done.
 
 Finally, reset controller handling as always gets merged through here
 as well.

Linus Torvalds f2b1e0f638 ARM: SoC cleanups and fixes for v4.7
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.

Linus Torvalds 1eccc6e152 This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
 
 - Support for natively single-ended GPIO driver stages. This
   means that if the hardware has registers to configure open
   drain or open source configuration, we use that rather than
   (as we did before) try to emulate it by switching the line
   to an input to get high impedance. This is also documented
   throughly in Documentation/gpio/driver.txt for those of you
   who did not understand one word of what I just wrote.
 
 - Start to do away with the unnecessarily complex and
   unitelligible ARCH_REQUIRE_GPIOLIB and
   ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
   the time when the GPIO subsystem was unmaintained. Archs can
   now just select GPIOLIB and be done with it, cleanups to
   arches will trickle in for the next kernel. Some minor archs
   ACKed the changes immediately so these are included in this
   pull request.
 
 - Advancing the use of the data pointer inside the GPIO device
   for storing driver data by switching the PowerPC, Super-H
   Unicore and a few other subarches or subsystem drivers in
   ALSA SoC, Input, serial, SSB, staging etc to use it.
 
 - The initialization now reads the input/output state of the
   GPIO lines, so that each GPIO descriptor knows - if this
   callback is implemented - whether the line is input or
   output. This also reflects nicely in userspace "lsgpio".
 
 - It is now possible to name GPIO producer names, line names,
   from the device tree. (Platform data has been supported for
   a while.) I bet we will get a similar mechanism for ACPI
   one of those days. This makes is possible to get sensible
   producer names for e.g. GPIO rails in "lsgpio" in userspace.
 
 New drivers:
 
 - New driver for the Loongson1.
 
 - The XLP driver now supports Broadcom Vulcan ARM64.
 
 - The IT87 driver now supports IT8620 and IT8628.
 
 - The PCA953X driver now supports Galileo Gen2.
 
 Driver improvements:
 
 - MCP23S08 was switched to use the gpiolib irqchip helpers and
   now also suppors level-triggered interrupts.
 
 - 74x164 and RCAR now supports the .set_multiple() callback
 
 - AMDPT was converted to use generic GPIO.
 
 - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
   support the new single ended callback for open drain
   and in some cases open source.
 
 - Implement the .get_direction() callback for a few more drivers
   like PL061, Xgene.
 
 Cleanups:
 
 - Paul Gortmaker combed through the drivers and de-modularized
   those who are not really modules.
 
 - Move the GPIO poweroff DT bindings to the power subdir where
   they belong.
 
 - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
   point. That's what it is handling, nothing more, nothing less.

Merge tag 'gpio-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for kernel cycle v4.7:

  Core infrastructural changes:

   - Support for natively single-ended GPIO driver stages.

     This means that if the hardware has registers to configure open
     drain or open source configuration, we use that rather than (as we
     did before) try to emulate it by switching the line to an input to
     get high impedance.

     This is also documented throughly in Documentation/gpio/driver.txt
     for those of you who did not understand one word of what I just
     wrote.

   - Start to do away with the unnecessarily complex and unitelligible
     ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
     evolutional artifact from the time when the GPIO subsystem was
     unmaintained.

     Archs can now just select GPIOLIB and be done with it, cleanups to
     arches will trickle in for the next kernel.  Some minor archs ACKed
     the changes immediately so these are included in this pull request.

   - Advancing the use of the data pointer inside the GPIO device for
     storing driver data by switching the PowerPC, Super-H Unicore and
     a few other subarches or subsystem drivers in ALSA SoC, Input,
     serial, SSB, staging etc to use it.

   - The initialization now reads the input/output state of the GPIO
     lines, so that each GPIO descriptor knows - if this callback is
     implemented - whether the line is input or output.  This also
     reflects nicely in userspace "lsgpio".

   - It is now possible to name GPIO producer names, line names, from
     the device tree.  (Platform data has been supported for a while).
     I bet we will get a similar mechanism for ACPI one of those days.
     This makes is possible to get sensible producer names for e.g.
     GPIO rails in "lsgpio" in userspace.

  New drivers:

   - New driver for the Loongson1.

   - The XLP driver now supports Broadcom Vulcan ARM64.

   - The IT87 driver now supports IT8620 and IT8628.

   - The PCA953X driver now supports Galileo Gen2.

  Driver improvements:

   - MCP23S08 was switched to use the gpiolib irqchip helpers and now
     also suppors level-triggered interrupts.

   - 74x164 and RCAR now supports the .set_multiple() callback

   - AMDPT was converted to use generic GPIO.

   - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
     support the new single ended callback for open drain and in some
     cases open source.

   - Implement the .get_direction() callback for a few more drivers like
     PL061, Xgene.

  Cleanups:

   - Paul Gortmaker combed through the drivers and de-modularized those
     who are not really modules.

   - Move the GPIO poweroff DT bindings to the power subdir where they
     belong.

   - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
     point.  That's what it is handling, nothing more, nothing less"

Jon Hunter a38045121b soc/tegra: pmc: Add generic PM domain support
Adds generic PM domain support to the PMC driver where the PM domains
are populated from device-tree and the PM domain consumer devices are
bound to their relevant PM domains via device-tree as well.

Update the tegra_powergate_sequence_power_up() API so that internally
it calls the same tegra_powergate_xxx functions that are used by the
Tegra generic PM domain code for consistency.

To ensure that the Tegra power domains (a.k.a. powergates) cannot be
controlled via both the legacy tegra_powergate_xxx functions as well
as the generic PM domain framework, add a bit map for available
powergates that can be controlled via the legacy powergate functions.

Move the majority of the tegra_powergate_remove_clamping() function
to a sub-function, so that this can be used by both the legacy and
generic power domain code.

This is based upon work by Thierry Reding <treding@nvidia.com>
and Vince Hsu <vinceh@nvidia.com>.

Geert Uytterhoeven 1c8c77f52d soc: renesas: rcar-sysc: Enable Clock Domain for I/O devices
On R-Car H3, some power areas (e.g. A3VP) contain I/O devices, which are
also part of the CPG/MSSR Clock Domain.
On all R-Car SoCs, devices in the "always-on" PM Domain are part of the
Clock Domain served by the CPG/MSSR or CPG/MSTP driver.

Hook up the CPG/MSTP or CPG/MSSR Clock Domain attach/detach callbacks to
enable power management using module clocks. Which callback to hook up
depends on the presence of device nodes compatible with
"renesas,cpg-mstp-clocks". This clears the path for a future migration
from the CPG/MSTP to the CPG/MSSR driver on R-Car H1 and
Gen2.

features of specific areas are obtained from tables in the C code.

The SYSCIER and SYSCIMR register values are derived from the power areas
present, which will help to get rid of the hardcoded values in R-Car H1
and R-Car Gen2 platform code later.

Initialization is done from an early_initcall(), to make sure the PM
Domains are initialized before secondary CPU bringup.

This patch fixes mt8173-evb failing boot issue. With commit [1],
genpd state will not sync to real power domain state. So some
resources such as clocks and regulators may stay in a wrong state.

There is no regulator double enabling issue on mainline kernel, so

Jon Hunter 0a2d87e047 soc/tegra: pmc: Wait for powergate state to change
Currently, the function tegra_powergate_set() simply sets the desired
powergate state but does not wait for the state to change. In most cases
we should wait for the state to change before proceeding. Currently,
there is a case for Tegra114 and Tegra124 devices where we do not wait
when starting the secondary CPU as this is not necessary. However, this
is only done at boot time and so waiting here will only have a small
impact on boot time. Therefore, update tegra_powergate_set() to wait
when setting the powergate.

By adding this feature, we can also eliminate the polling loop from
tegra30_boot_secondary().

A function has been added for checking the status of the powergate and
so update the tegra_powergate_is_powered() to use this macro as well.

Jon Hunter bc9af23d31 soc/tegra: pmc: Ensure GPU partition can be toggled on/off by PMC
For Tegra124 and Tegra210, the GPU partition cannot be toggled on and
off via the APBDEV_PMC_PWRGATE_TOGGLE_0 register. For these devices, the
partition is simply powered up and down via an external regulator.
For these devices, there is a separate register for controlling the
signal clamping of the partition and this is described in the PMC SoC
data by the "has_gpu_clamp" variable. Use this variable to determine if
the GPU partition can be controlled via the APBDEV_PMC_PWRGATE_TOGGLE_0
register and ensure that no one can incorrectly try to toggle the GPU
partition via the APBDEV_PMC_PWRGATE_TOGGLE_0 register.

Furthermore, we cannot use the APBDEV_PMC_PWRGATE_STATUS_0 register to
determine if the GPU partition is powered for Tegra124 and Tegra210.
However, if the GPU partition is powered, then the signal clamp for the
GPU partition should be removed and so use bit 0 of the
APBDEV_PMC_GPU_RG_CNTRL_0 register to determine if the clamp has been
removed (bit[0] = 0) and the GPU partition is powered.

Jon Hunter 0a243bd438 soc/tegra: pmc: Fix verification of valid partitions
The Tegra power partitions are referenced by numerical IDs which are the
same values programmed into the PMC registers for controlling the
partition. For a given device, the valid partition IDs may not be
contiguous and so simply checking that an ID is not greater than the
maximum ID supported may not mean it is valid. Fix this by checking if
the powergate is defined in the list of powergates for the Tegra SoC.

Add a helper function for checking valid powergates and use where we
need to verify if the powergate ID is valid or not.

Jon Hunter 0ecf2d33bb soc/tegra: pmc: Fix testing of powergate state
In tegra_powergate_set() the state of the powergates is read and OR'ed
with the bit for the powergate of interest. This unsigned 32-bit value
is then compared with a boolean value to test if the powergate is
already in the desired state. When turning on a powergate, apart from
the powergate that is represented by bit 0, this test will always
return false and so we may attempt to turn on the powergate when it is
already on.

After OR'ing the bit for the powergate, check if the result is not equal
to zero before comparing with the boolean value. Add a helper function
to return the current state of a powergate and use this in both
tegra_powergate_set() and tegra_powergate_is_powered() where we check
the powergate status.

Jon Hunter e8cf6616a3 soc/tegra: pmc: Protect public functions from potential race conditions
The PMC base address pointer is initialised during early boot so that
early platform code may used the PMC public functions. During the probe
of the PMC driver the base address pointer is mapped again and the initial
mapping is freed. This exposes a window where a device accessing the PMC
registers via one of the public functions, could race with the updating
of the pointer and lead to a invalid access. Furthermore, the only
protection between multiple devices attempting to access the PMC registers
is when setting the powergate state to on or off. None of the other public
functions that access the PMC registers are protected.

Use the existing mutex to protect paths that may race with regard to
accessing the PMC registers.

Note that functions tegra_io_rail_prepare()/poll() either return a
negative value on failure or zero on success. Therefore, it is not
necessary to check if the return value is less than zero and so only
test that the return value is not zero to test for failure. This
simplifies the error handling with the mutex locking in place.

Jon Hunter 0259f522e0 soc/tegra: pmc: Restore base address on probe failure
During early initialisation, the PMC registers are mapped and the PMC SoC
data is populated in the PMC data structure. This allows other drivers
access the PMC register space, via the public Tegra PMC APIs, prior to
probing the PMC device.

When the PMC device is probed, the PMC registers are mapped again and if
successful the initial mapping is freed. If the probing of the PMC device
fails after the registers are remapped, then the registers will be
unmapped and hence the pointer to the PMC registers will be invalid. This
could lead to a potential crash, because once the PMC SoC data pointer is
populated, the driver assumes that the PMC register mapping is also valid
and a user calling any of the public Tegra PMC APIs could trigger an
exception because these APIs don't check that the mapping is still valid.

Fix this by updating the mapping and freeing the original mapping only if
probing the PMC device is successful.

Arnd Bergmann cc0336ec8a soc: TI knav_qmss: fix dma_addr_t printing
The knav_qmss driver is currently broken when CONFIG_LPAE is
set, which is a bit surprising because I'd expect that any serious
users of this platforms would have more than 2GB of RAM and require
LPAE.

The compiler clearly warns about an incorrect use of dma_addr_t
in the debug kernel messages:

ti/knav_qmss_queue.c: In function 'knav_queue_setup_region':
ti/knav_qmss_queue.c:1025:117: warning: format '%x' expects argument of type 'unsigned int', but argument 9 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]
ti/knav_qmss_queue.c:1025:117: warning: format '%x' expects argument of type 'unsigned int', but argument 10 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]
ti/knav_qmss_queue.c: In function 'knav_queue_setup_link_ram':
ti/knav_qmss_queue.c:1175:118: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

This patch changes all the debugging output to use the correct
%pad format string that works with both 32-bit and 64-bit dma_addr_t.
As the variable naming is somewhat confusing here, I also change
all *_phys names to *_dma when they refer to bus addresses that
are used for DMA rather than a physical memory address as seen from
the CPU. This is particularly important on keystone, because the
two things are not the same there.

This patch moves Exynos PMU driver implementation from "arm/mach-exynos"
to "drivers/soc/samsung". This driver is mainly used for setting misc
bits of register from PMU IP of Exynos SoC which will be required to
configure before Suspend/Resume. Currently all these settings are done
in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC
support, there is a need of this PMU driver in driver/* folder.

This driver uses existing DT binding information and there should
be no functionality change in the supported platforms.

FSM_VLDCLR state when data send back later by PMIC and timeout again in next
time because pmic wrap waiting for FSM_IDLE state at the beginning of the
read/write function.

Clear the vldclr when timeout if state machine stay on FSM_VLDCLR.

Linus Walleij e847396b40 powerpc: qe_lib/gpio: Be sure to clamp return value
As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

Linus Torvalds 79d245327f ARM: SoC support for Tegra platforms for v4.5
Here's a single-SoC topic branch that we've staged separately. Mainly
 because it was hard to sort the branch contents in a way that fit our
 existing branches due to some refactorings.
 
 The code has been in -next for quite a while, but we staged it in arm-soc
 a bit late, which is why we've kept it separate from the other updates
 and are sending it separately here.

gcc warns about the 'found' variable possibly being used uninitialized:

drivers/soc/qcom/spm.c:305:5: error: 'found' may be used uninitialized in this function [-Werror=maybe-uninitialized]

However, the code is correct because we know that there is
always at least one online CPU. This initializes the 'found'
variable to zero before the loop so the compiler knows
it does not have to warn about it.

 - Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
   parts of the chip/board on these platforms, all proprietary protocols that
   don't fit into other subsystems and live in drivers/soc for now.
 
 - System bus driver for UniPhier

 - Power management for Raspberry PI

Linus Torvalds 6b5a12dbca ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6
 and ARMv7 platforms together such that they can all be enabled and
 boot the same kernel. It has been a tremendous amount of cleanup and
 refactoring by a huge number of people, and creation of several new
 (and major) subsystems to better abstract out all the platform details
 in an appropriate manner.
 
 The bulk of this branch is a large patchset from Arnd that brings several
 of the more minor and older platforms we have closer to multiplatform
 support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
 Much of this is moving around header files from old mach directories,
 but there are also some cleanup patches of debug_ll (lowlevel debug
 per-platform options) and other parts.
 
 Linus Walleij also has some patchs to clean up the older ARM Realview
 platforms by finally introducing DT support, and Rob Herring has some
 for ARM Versatile which is now DT-only. Both of these platforms are
 now multiplatform.
 
 Finally, a couple of patches from Russell for Dove PMU, and a fix from
 Valentin Rothberg for Exynos ADC, which were rebased on top of the
 series to avoid conflicts.

Arnd Bergmann 22a5b1ddd8 ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency
The firmware driver can be a loadable module, but the power domain
can only be built-in, so we get a build error in an allmodconfig
kernel:

:(.text+0x17e59c): undefined reference to `rpi_firmware_property'
:(.text+0x17e51c): undefined reference to `rpi_firmware_get'
:(.text+0x17e244): undefined reference to `rpi_firmware_property'

This changes the dependency to only allow the power domain code
to be enabled when the firmware driver is built-in. Other users
of the firmware driver may still be loadable modules and not
everyone needs the power domains, so we don't change the firmware
code.

Lorenzo Pieralisi f6419f240b ARM: 8485/1: cpuidle: remove cpu parameter from the cpuidle_ops suspend hook
The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.

This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.

This patch adds support for several power domains on Raspberry Pi,
including USB (so it can be enabled even if the bootloader didn't do
it), and graphics.

This patch is the combined work of Eric Anholt (who wrote USB support
inside of the Raspberry Pi firmware driver, and wrote the non-USB
domain support) and Alexander Aring (who separated the original USB
work out from the firmware driver).

Paul Gortmaker e50be5cd0c drivers/soc: make mediatek/mtk-scpsys.c explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/soc/mediatek/Kconfig:config MTK_SCPSYS
drivers/soc/mediatek/Kconfig:   bool "MediaTek SCPSYS Support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Michal Morawiec f7f2bccd1f soc: ti: knav_qmss_queue: Fix linking RAM setup for queue managers
Configure linking RAM for both queue managers also in case
when only linking RAM 0 is specified in device tree.

Currently hwqueue driver configures linking RAM(s) to be used
cooperatively by the QMs (shared mode). Therefore if both
queue managers are used then both must be configured with
exactly the same linking RAM info (base address and size)
independent of the number of linking RAM(s) specified in the
device tree.
For proper operation only one linking RAM is required and in most
cases this can be internal one as long as it is able to handle
the number of descriptors used in the system.
Current driver code however skips configuration of second
queue manager if second linking RAM is not specified.
If the configuration for the QM2 is missing there will be
a crash when it tries to push/pop descriptors from its queues.

Linus Torvalds b44a3d2a85 ARM: SoC driver updates for v4.4
As we've enabled multiplatform kernels on ARM, and greatly done away with
 the contents under arch/arm/mach-*, there's still need for SoC-related
 drivers to go somewhere.
 
 Many of them go in through other driver trees, but we still have
 drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
 that might be shared between ARM and ARM64 (or just in general makes
 sense to not have under the architecture directory).
 
 This branch contains mostly such code:
 
 - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
   with power management blocks on these SoCs for use by clock, regulator and
   bus frequency drivers.
 - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
 - Drivers for ARM's SCPI (System Control Processor). Not to be confused with
   PSCI (Power State Coordination Interface). SCPI is used to communicate with
   the assistant embedded cores doing power management, and we have yet to see
   how many of them will implement this for their hardware vs abstracting in
   other ways (or not at all like in the past).
 - To make confusion between SCPI and PSCI more likely, this release also
   includes an update of PSCI to interface version 1.0.
 - Rockchip support for power domains.
 - A driver to talk to the firmware on Raspberry Pi.

Stephen Boyd d0bfd7c9b1 soc: qcom: smem: Move RPM message ram out of smem DT node
SMEM is a software construct built on top of a DDR reserved region
and sometimes a device memory region called RPM message ram. Having
the RPM message ram in the smem DT node's reg property leads to the
smem node being located in different places depending on if the
message ram is being used or not. Let's add a qcom specific
property, qcom,rpm-msg-ram, and point to the device memory from
the SMEM node via a phandle.  As SMEM is a software construct, it
really needs to reside at the root of the DT regardless of whether
it's using the message ram or not.

Instead of littering the code with casts every time this function
is called, have qcom_smem_get() return a void pointer to the
location of the smem item. This frees the caller from having to
cast the pointer.

James Liao 41b3e0f067 soc: mediatek: Fix random hang up issue while kernel init
In kernel late init, it turns off all unused clocks, which
needs to access subsystem registers such as VENC and VENC_LT.

Accessing MT8173 VENC registers needs two top clocks, mm_sel and
venc_sel. Accessing VENC_LT registers needs mm_sel and venclt_sel.
So we need to keep these clocks on before accessing their registers.

This patch keeps venc_sel / venclt_sel clock on when
VENC / VENC_LT's power is on, to prevent system hang up while
accessing its registeres.

Murali Karicheri 96ee19becc soc: ti: add firmware file name as part of the driver
Currently firmware file name is included in the DTS. This is not scalable
as user has to change the DTS if they need upgrade to a new firmware.
Instead, add the firmware file name in the driver itself. As long as there
is no API change, new firmware upgrade is easy and require no driver
change. User is expected to copy the firmware image to the file system
and add a sym link to the new firmware for doing an upgrade. Driver add
a array of firmware file names to search for the available firmware blobs.
This scheme also prepare the driver for future changes to API if ever
happens. In such case it is assumed that driver needs to change to
accommodate the new firmware and new firmware file name will get added to
the array.

Also update the DT document to remove the firmware attribute and add
description about firmware in the driver documentation.

This driver is found on RK3288 SoCs.

In order to meet high performance and low power requirements, a power
management unit is designed or saving power when RK3288 in low power
mode.
The RK3288 PMU is dedicated for managing the power of the whole chip.

PMU can work in the Low Power Mode by setting bit[0] of PMU_PWRMODE_CON
register. After setting the register, PMU would enter the Low Power mode.
In the low power mode, pmu will auto power on/off the specified power
domain, send idle req to specified power domain, shut down/up pll and
so on. All of above are configurable by setting corresponding registers.

Linus Torvalds 102178108e ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:

 "Some releases this branch is nearly empty, others we have more stuff.
  It tends to gather drivers that need SoC modification or dependencies
  such that they have to (also) go in through our tree.

  For this release, we have merged in part of the reset controller tree
  (with handshake that the parts we have merged in will remain stable),
  as well as dependencies on a few clock branches.

  In general, new items here are:

   - Qualcomm driver for SMM/SMD, which is how they communicate with the
     coprocessors on (some) of their platforms

   - memory controller work for ARM's PL172 memory controller

   - reset drivers for various platforms

Russell King 44e259ac90 ARM: dove: create a proper PMU driver for power domains, PMU IRQs and resets
The PMU device contains an interrupt controller, power control and
resets.  The interrupt controller is a little sub-standard in that
there is no race free way to clear down pending interrupts, so we try
to avoid problems by reducing the window as much as possible, and
clearing as infrequently as possible.

The interrupt support is implemented using an IRQ domain, and the
parent interrupt referenced in the standard DT way.

The power domains and reset support is closely related - there is a
defined sequence for powering down a domain which is tightly coupled
with asserting the reset.  Hence, it makes sense to group these two
together, and in order to avoid any locking contention disrupting this
sequence, we avoid the use of syscon or regmap.

This patch adds the core PMU driver: power domains must be defined in
the DT file in order to make use of them.  The reset controller can
be referenced in the standard way for reset controllers.

inside the SCPSYS is for the MTCMOS power domain control.

For now this driver only adds power domain support, the more
advanced features are not yet supported. The driver implements
the generic PM domain device tree bindings, the first user will

Merge tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull module_platform_driver replacement from Paul Gortmaker:
 "Replace module_platform_driver with builtin_platform driver in non
  modules.

  We see an increasing number of non-modular drivers using
  modular_driver() type register functions.  There are several downsides
  to letting this continue unchecked:

   - The code can appear modular to a reader of the code, and they won't
     know if the code really is modular without checking the Makefile
     and Kconfig to see if compilation is governed by a bool or
     tristate.

   - Coders of drivers may be tempted to code up an __exit function that
     is never used, just in order to satisfy the required three args of
     the modular registration function.

   - Non-modular code ends up including the <module.h> which increases
     CPP overhead that they don't need.

   - It hinders us from performing better separation of the module init
     code and the generic init code.

  So here we introduce similar macros for builtin drivers.  Then we
  convert builtin drivers (controlled by a bool Kconfig) by making the
  following type of mapping:

    module_platform_driver()       --->  builtin_platform_driver()
    module_platform_driver_probe() --->  builtin_platform_driver_probe().

  The set of drivers that are converted here are just the ones that
  showed up as relying on an implicit include of <module.h> during a
  pending header cleanup.  So we convert them here vs adding an include
  of <module.h> to non-modular code to avoid compile fails.  Additonal
  conversions can be done asynchronously at any time.

  Once again, an unused module_exit function that is removed here
  appears in the diffstat as an outlier wrt all the other changes"

Stephen Boyd 498f09bce4 soc: qcom: spm: Fix idle on THUMB2 kernels
The ifc6410 firmware always enters the kernel in ARM state from
deep idle. Use the cpu_resume_arm() wrapper instead of
cpu_resume() to property switch into the THUMB2 state when we
wake up from idle.

This fixes a problem reported by Kevin Hilman on next-20150601
where the ifc6410 fails to boot a THUMB2 kernel because the
platform's firmware always enters the kernel in ARM mode from
deep idle states.

Maxime Ripard 4af34b572a drivers: soc: sunxi: Introduce SoC driver to map SRAMs
The Allwinner SoCs have a handful of SRAM that can be either mapped to be
accessible by devices or the CPU.

That mapping is controlled by an SRAM controller, and that mapping might
not be set by the bootloader, for example if the device wasn't used at all,
or if we're using solutions like the U-Boot's Falcon Boot.

We could also imagine changing this at runtime for example to change the
mapping of these SRAMs to use them for suspend/resume or runtime memory
rate change, if that ever happens.

These use cases require some API in the kernel to control that mapping,
exported through a drivers/soc driver.

This driver also implement a debugfs file that shows the SRAM found in the
system, the current mapping and the SRAM that have been claimed by some
drivers in the kernel.

Sascha Hauer d956b80ac7 soc: mediatek: PMIC wrap: Fix register state machine handling
When the PMIC wrapper state machine has read a register it goes into the
"wait for valid clear" (vldclr) state. The state machine stays in this
state until the VLDCLR bit is written to. We should write this bit after
reading a register because the SCPSYS won't let the system go into
suspend as long as the state machine waits for valid clear.

Since now we never leave the state machine in vldclr state we no longer
have to check for this state on pwrap_read/pwrap_write entry and can
remove the corresponding code.

Sascha Hauer d71c11f3bd soc: mediatek: PMIC wrap: Fix clock rate handling
replace chipselect extension values based on SPI clock with hardcoded SoC
specific values.

The PMIC wrapper has the ability of extending the chipselects by configurable
amounts of time. We configured the values based on the rate of SPI clock, but
this is wrong. The delays should be configured based on the internal PMIC clock
that latches the values from the SPI bus to the internal PMIC registers. By
default this clock is 24MHz. Other clock frequencies are for debugging only
and can be removed from the driver.

Lina Iyer 7ce75bb2c0 ARM: qcom: Add Subsystem Power Manager (SPM) driver
SPM is a hardware block that controls the peripheral logic surrounding
the application cores (cpu/l$). When the core executes WFI instruction,
the SPM takes over the putting the core in low power state as
configured. The wake up for the SPM is an interrupt at the GIC, which
then completes the rest of low power mode sequence and brings the core
out of low power mode.

The SPM has a set of control registers that configure the SPMs
individually based on the type of the core and the runtime conditions.
SPM is a finite state machine block to which a sequence is provided and
it interprets the bytes and executes them in sequence. Each low power
mode that the core can enter into is provided to the SPM as a sequence.

Configure the SPM to set the core (cpu or L2) into its low power mode,
the index of the first command in the sequence is set in the SPM_CTL
register. When the core executes ARM wfi instruction, it triggers the
SPM state machine to start executing from that index. The SPM state
machine waits until the interrupt occurs and starts executing the rest
of the sequence until it hits the end of the sequence. The end of the
sequence jumps the core out of its low power mode.

Add support for an idle driver to set up the SPM to place the core in
Standby or Standalone power collapse mode when the core is idle.

This adds support for the PMIC wrapper found on MediaTek MT8135 and
MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these
are currently not supported.

On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via
SPI. The SPI master interface is not directly visible to the CPU, but
only through the PMIC wrapper inside the SoC. The communication between
the SoC and the PMIC can optionally be encrypted. Also a non standard
Dual IO SPI mode can be used to increase speed. The MT8135 also supports
a special feature named "IP Pairing". With IP Pairing the pins of some
SoC internal peripherals can be on the PMIC. The signals of these pins
are routed over the SPI bus using the pwrap bridge. Because of these
optional non SPI conform features the PMIC driver is not implemented as
a SPI bus master driver.

This adds a device tree controlled option to enable PMC-based
thermal reset in overheating situations. Thermtrip is supported on
Tegra30, Tegra114 and Tegra124. The thermal reset only works when
the thermal sensors are calibrated, so a soctherm driver is also
required.

The thermtrip event is triggered by the soctherm block, and all
soctherm sensors default to showing a temperature of zero Celsius
before they are initialized. Because of this, it is safe to initialize
thermtrip and soctherm in any order.

low-power states in mainline Linux.  When this support is added in the

Pull drm updates from Dave Airlie:
 "Highlights:

   - AMD KFD driver merge

     This is the AMD HSA interface for exposing a lowlevel interface for
     GPGPU use.  They have an open source userspace built on top of this
     interface, and the code looks as good as it was going to get out of
     tree.

   - Initial atomic modesetting work

     The need for an atomic modesetting interface to allow userspace to
     try and send a complete set of modesetting state to the driver has
     arisen, and been suffering from neglect this past year.  No more,
     the start of the common code and changes for msm driver to use it
     are in this tree.  Ongoing work to get the userspace ioctl finished
     and the code clean will probably wait until next kernel.

   - DisplayID 1.3 and tiled monitor exposed to userspace.

     Tiled monitor property is now exposed for userspace to make use of.

   - Rockchip drm driver merged.

   - imx gpu driver moved out of staging

  Other stuff:

   - core:
        panel - MIPI DSI + new panels.
        expose suggested x/y properties for virtual GPUs

   - i915:

Linus Torvalds e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

Linus Torvalds 3a647c1d7a ARM: SoC driver updates for 3.19
These are changes for drivers that are intimately tied to some SoC
 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 The largest single change here this time around is the Tegra
 iommu/memory controller driver, which gets updated to the new
 iommu DT binding. More drivers like this are likely to follow
 for the following merge window, but we should be able to do
 those through the iommu maintainer.
 
 Other notable changes are:
 * reset controller drivers from the reset maintainer (socfpga, sti, berlin)
 * fixes for the keystone navigator driver merged last time
 * at91 rtc driver changes related to the at91 cleanups
 * ARM perf driver changes from Will Deacon
 * updates for the brcmstb_gisb driver

   directories
 - socfpga: add edac driver (through arm-soc, as requested by Boris)

This adds a SoC driver to be used by the ARM RealView
reference boards. We create the "versatile" directory to hold
the different ARM reference designs as per the pattern of the
clk directory layout. The driver utilze the syscon to get to
the register needed. After this we can use sysfs to get at
some SoC properties on RealView DT variants like this:

Santosh Shilimkar 88139ed030 soc: ti: add Keystone Navigator DMA support
The Keystone Navigator DMA driver sets up the dma channels and flows for
the QMSS(Queue Manager SubSystem) who triggers the actual data movements
across clients using destination queues. Every client modules like
NETCP(Network Coprocessor), SRIO(Serial Rapid IO) and CRYPTO
Engines has its own instance of packet dma hardware. QMSS has also
an internal packet DMA module which is used as an infrastructure
DMA with zero copy.

Initially this driver was proposed as DMA engine driver but since the
hardware is not typical DMA engine and hence doesn't comply with typical
DMA engine driver needs, that approach was naked. Link to that
discussion -
	https://lkml.org/lkml/2014/3/18/340

As aligned, now we pair the Navigator DMA with its companion Navigator
QMSS subsystem driver.

Sandeep Nair 41f93af900 soc: ti: add Keystone Navigator QMSS driver
The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
the main hardware sub system which forms the backbone of the Keystone
Multi-core Navigator. QMSS consist of queue managers, packed-data structure
processors(PDSP), linking RAM, descriptor pools and infrastructure
Packet DMA.

The Queue Manager is a hardware module that is responsible for accelerating
management of the packet queues. Packets are queued/de-queued by writing or
reading descriptor address to a particular memory mapped location. The PDSPs
perform QMSS related functions like accumulation, QoS, or event management.
Linking RAM registers are used to link the descriptors which are stored in
descriptor RAM. Descriptor RAM is configurable as internal or external memory.

The QMSS driver manages the PDSP setups, linking RAM regions,
queue pool management (allocation, push, pop and notify) and descriptor
pool management. The specifics on the device tree bindings for
QMSS can be found in:

Srinivas Kandagatla fa9eb32418 drivers/soc: qcom: do not disable the iface clock in probe
since commit 31964ffebb ("tty: serial: msm: Remove direct access to GSBI")'
serial hangs if earlyprintk are enabled.

This hang is noticed only when the GSBI driver is probed and all the
earlyprintks before gsbi probe are seen on the console.
The reason why it hangs is because GSBI driver disables hclk in its
probe function without realizing that the serial IP might be in use by
a bootconsole. As gsbi driver disables the clock in probe the
bootconsole locks up.

Turning off hclk's could be dangerous if there are system components
like earlyprintk using the hclk.

This patch fixes the issue by delegating the clock management to
probe and remove functions in gsbi rather than disabling the clock in probe.

More detailed problem description can be found here:

Thierry Reding 7232398abc ARM: tegra: Convert PMC to a driver
This commit converts the PMC support code to a platform driver. Because
the boot process needs to call into this driver very early, also set up

Thierry Reding 24fa5af810 soc/tegra: fuse: Set up in early initcall
Rather than rely on explicit initialization order called from SoC setup
code, use a plain initcall and rely on initcall ordering to take care of
dependencies.

This driver exposes some functionality (querying the chip ID) needed at
very early stages of the boot process. An early initcall is good enough
provided that some of the dependencies are deferred to later stages. To
make sure any abuses are easily caught, output a warning message if the
chip ID is queried while it can't be read yet.

The Tegra20 fuse driver is the only user of tegra_apb_readl_using_dma().
Therefore we can simply the code by incorporating the APB DMA handling into
the driver directly. tegra_apb_writel_using_dma() is dropped because there
are no users.
