"Sorry for delaying this a bit later than usual. There's one mild
regression from 3.16 that was noticed during the 3.17 cycle, and I
meant to send a fix for it along with this pull request. I'll
probably try to queue it up for a later pull request once I've had a
better look at it, hopefully by -rc2 at the latest.

fixes and enhancements to existing drivers as well as new drivers. This
tag contains a bit more arch code than I usually take due to some OMAP2+
changes. Additionally it contains the restart notifier handlers which
are merged as a dependency into several trees.
The PXA changes are the only messy part. Due to having a stable tree I
had to revert one patch and follow up with one more fix near the tip of
this tag. Some dead code is introduced but it will soon become live code
after 3.18-rc1 is released as the rest of the PXA family is converted
over to the common clock framework.
Another trend in this tag is that multiple vendors have started to push
the complexity of changing their CPU frequency into the clock driver,
whereas this used to be done in CPUfreq drivers.
Changes to the clk core include a generic gpio-clock type and a
clk_set_phase() function added to the top-level clk.h api. Due to some
confusion on the fbdev mailing list the kernel boot parameters
documentation was updated to further explain the clk_ignore_unused
parameter, which is often required by users of the simplefb driver.
Finally some fixes to the locking around the clock debugfs stuff was
done to prevent deadlocks when interacting with other subsystems.

- Rework the handling of wakeup IRQs by the IRQ core such that
all of them will be switched over to "wakeup" mode in
suspend_device_irqs() and in that mode the first interrupt
will abort system suspend in progress or wake up the system
if already in suspend-to-idle (or equivalent) without executing
any interrupt handlers. Among other things that eliminates the
wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
flag with interrupts which don't really need it and should not
use it (Thomas Gleixner and Rafael J Wysocki).
- Switch over ACPI to handling wakeup interrupts with the help
of the new mechanism introduced by the above IRQ core rework
(Rafael J Wysocki).
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during
enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in
the METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot
(or after resume from system suspend) and rework the ACPI Smart
Battery Subsystem (SBS) driver to work correctly with Apple
platforms (Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
code, adding support for 133MHz I2C source clock on Intel Baytrail
to it and making it avoid using UART RTS override with Auto Flow
Control (Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).

them will be switched over to "wakeup" mode in suspend_device_irqs()
and in that mode the first interrupt will abort system suspend in
progress or wake up the system if already in suspend-to-idle (or

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.
Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.
This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

In order to handle errata I688, a page of sram was reserved by doing a
static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.

Use drivers/misc/sram.c driver to manage SRAM on all DT only
OMAP platforms (am33xx, am43xx, omap4 and omap5) instead of
the existing private plat-omap/sram.c
Address and size related data is removed from mach-omap2/sram.c
and now passed to drivers/misc/sram.c from DT.
Users can hence use general purpose allocator apis instead of
OMAP private ones to manage and use SRAM.

As we have support for this in board-rx51-peripherals.c, let's
add it to the .dts files too.
Note that the reset GPIO will eventually go to the driver.
For now let's just pull it down and skip any further reset
in case the bootloader has configured the MAC address so
NFSroot works.
Also note that after 3430-sdp are using proper GPMC timings
we can remove the tests for smsc,lan91c94 in gpmc.c.

In sprz318f.pdf "Usage Note 2.7" says that UARTs cannot acknowledge
idle requests in smartidle mode when configured for DMA operations.
This prevents L4 from going idle. So let's use manual idle mode
instead.
Otherwise systems using Sebastian's 8250 patches with DMA will
never enter deeper idle states because of the errata above.

Commit cc824534d4 ("ARM: OMAP2+: hwmod: Rearm wake-up interrupts
for DT when MUSB is idled") fixed issues with hung UART wake-up
events by calling _reconfigure_io_chain() when MUSB is connected
or disconnected.
As pointed out by Paul Walmsley, we may need to also call
_reconfigure_io_chain() in other cases, so it should be a separate
flag. Let's add HWMOD_RECONFIG_IO_CHAIN as suggested by Paul.

the 'nand-on-flash-bbt' devicetree property.
If the flash BBT is not enabled, the driver falls back to use OOB
bad block markers only, as before. If the flash BBT is enabled the
kernel will keep track of bad blocks using a BBT, in addition to
the OOB markers.
As explained by Brian Norris the reasons for using a BBT are:
""
The primary reason would be that NAND datasheets specify it these days.
A better argument is that nobody guarantees that you can write a
bad block marker to a worn out block; you may just get program failures.
This has been acknowledged by several developers over the last several
years.
Additionally, you get a boot-time performance improvement if you only
have to read a few pages, instead of a page or two from every block on
the flash.

We are getting "PRM: I/O chain clock line assertion timed out" errors
on early omaps for device tree based booting. This is because we are
unconditionally calling reconfigure_io_chain while legacy booting
has omap3_has_io_chain_ctrl() checks in place in omap_hwmod.c.
For device tree based booting, we are calling reconfigure_io_chain
unconditionally from pinctrl framework. So we need to add a check for
omap3_has_io_chain_ctrl() to avoid the errors for trying to access
a register that does not exist.
For es3.0, the documentation in "4.11.2 Device Off-Mode Configuration"
just mentions PM_WKEN_WKUP[8] bit. For es3.1, there's a new chapter in
documentation for "4.11.2.2 I/O Wake-Up Mechanism" that describes the
PM_WKEN_WKUP[16] ST_IO_CHAIN bit. So PM_WKEN_WKUP[16] bit did not get
added until in es3.1 probaly to fix issues with flakey wake-up events.
We are doing proper checks for ST_IO_CHAIN already in id.c and with
omap3_has_io_chain_ctrl(). For more information, see also commit
b02b917211 ("ARM: OMAP3: PM: fix I/O wakeup and I/O chain clock
control detection").
Let's fix the issue by selecting the right function during init for
reconfigure_io_chain depending on the omap revision. For es3.0 and
earlier we need to just toggle EN_IO. By doing this, we can move the
check for omap3_has_io_chain_ctrl() from omap_hwmod.c to the init code
in prm_3xxx.c. And then we can unconditionally call reconfigure_io_chain.
Thanks to Paul Walmsley and Nishanth Menon for help with debugging the
issue.

Looks like MUSB cable removal can cause wake-up interrupts to
stop working for device tree based booting at least for UART3
even as nothing is dynamically remuxed. This can be fixed by
calling reconfigure_io_chain() for device tree based booting
in hwmod code. Note that we already do that for legacy booting
if the legacy mux is configured.
My guess is that this is related to UART3 and MUSB ULPI
hsusb0_data0 and hsusb0_data1 support for Carkit mode that
somehow affect the configured IO chain for UART3 and require
rearming the wake-up interrupts.
In general, for device tree based booting, pinctrl-single
calls the rearm hook that in turn calls reconfigure_io_chain
so calling reconfigure_io_chain should not be needed from the
hwmod code for other events.
So let's limit the hwmod rearming of iochain only to
HWMOD_FORCE_MSTANDBY where MUSB is currently the only user
of it. If we see other devices needing similar changes we can
add more checks for it.

When an alias for a clock already exists the warning is printed. For
every module with a main_clk defined, a clk alias for fck is added.
There are some components that have the same main_clk defined, so this
is a really normal situation.
For example the am33xx edma device has 4 components using the same main
clock. So there are three warnings in the boot log for this already
existing clock alias:
platform 49000000.edma: alias fck already exists
platform 49000000.edma: alias fck already exists
platform 49000000.edma: alias fck already exists
As this is only interesting for developers, this patch changes the
message to a debug message.

For v3.14 and prior, 1-bit Hamming code ECC via software was the
default choice for some boards e.g. 3430sdp.
Commit ac65caf514 in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So don't mark "sw" scheme
as deperecated and support it.

For v3.12 and prior, 1-bit Hamming code ECC via software was the
default choice. Commit c66d039197 in v3.13 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.12

using software ECC by default if an ECC scheme is not explicitely
specified.

Note that these are based on earlier omap-for-v3.17/soc.
No strict dependency to it though, but I already merged in
the pull request from Paul for the first fix into it and
these are all SoC related.

Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an Ippo

* Allwinner A31 Hummingbird board support, not to be confused with the

* Tegra30 Apalis board support

Pull ACPI and power management updates from Rafael Wysocki:
"Again, ACPICA leads the pack (47 commits), followed by cpufreq (18
commits) and system suspend/hibernation (9 commits).
From the new code perspective, the ACPICA update brings ACPI 5.1 to
the table, including a new device configuration object called _DSD
(Device Specific Data) that will hopefully help us to operate device
properties like Device Trees do (at least to some extent) and changes
related to supporting ACPI on ARM.
Apart from that we have hibernation changes making it use radix trees
to store memory bitmaps which should speed up some operations carried
out by it quite significantly. We also have some power management
changes related to suspend-to-idle (the "freeze" sleep state) support
and more preliminary changes needed to support ACPI on ARM (outside of
ACPICA).
The rest is fixes and cleanups pretty much everywhere.
Specifics:
- ACPICA update to upstream version 20140724. That includes ACPI 5.1
material (support for the _CCA and _DSD predefined names, changes
related to the DMAR and PCCT tables and ARM support among other
things) and cleanups related to using ACPICA's header files. A
major part of it is related to acpidump and the core code used by
that utility. Changes from Bob Moore, David E Box, Lv Zheng,
Sascha Wildner, Tomasz Nowicki, Hanjun Guo.
- Radix trees for memory bitmaps used by the hibernation core from
Joerg Roedel.
- Support for waking up the system from suspend-to-idle (also known
as the "freeze" sleep state) using ACPI-based PCI wakeup signaling
(Rafael J Wysocki).
- Fixes for issues related to ACPI button events (Rafael J Wysocki).
- New device ID for an ACPI-enumerated device included into the
Wildcat Point PCH from Jie Yang.
- ACPI video updates related to backlight handling from Hans de Goede
and Linus Torvalds.
- Preliminary changes needed to support ACPI on ARM from Hanjun Guo
and Graeme Gregory.
- ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui.
- Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros
(Rafael J Wysocki).
- ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J
Wysocki.
- Cleanups and improvements related to system suspend from Lan

Pull ARM updates from Russell King:
"Included in this update:
- perf updates from Will Deacon:
The main changes are callchain stability fixes from Jean Pihet and
event mapping and PMU name rework from Mark Rutland
The latter is preparatory work for enabling some code re-use with
arm64 in the future.
- updates for nommu from Uwe Kleine-König:
Two different fixes for the same problem making some ARM nommu
configurations not boot since 3.6-rc1. The problem is that
user_addr_max returned the biggest available RAM address which
makes some copy_from_user variants fail to read from XIP memory.
- deprecate legacy OMAP DMA API, in preparation for it's removal.
The popular drivers have been converted over, leaving a very small
number of rarely used drivers, which hopefully can be converted
during the next cycle with a bit more visibility (and hopefully
people popping out of the woodwork to help test)
- more tweaks for BE systems, particularly with the kernel image
format. In connection with this, I've cleaned up the way we
generate the linker script for the decompressor.
- removal of hard-coded assumptions of the kernel stack size, making
everywhere depend on the value of THREAD_SIZE_ORDER.
- MCPM updates from Nicolas Pitre.
- Make it easier for proper CPU part number checks (which should
always include the vendor field).
- Assembly code optimisation - use the "bx" instruction when
returning from a function on ARMv6+ rather than "mov pc, reg".
- Save the last kernel misaligned fault location and report it via
the procfs alignment file.
- Clean up the way we create the initial stack frame, which is a
repeated pattern in several different locations.
- Support for 8-byte get_user(), needed for some DRM implementations.
- mcs locking from Will Deacon.
- Save and restore a few more Cortex-A9 registers (for errata
workarounds)
- Fix various aspects of the SWP emulation, and the ELF hwcap for the
SWP instruction.
- Update LPAE logic for pte_write and pmd_write to make it more
correct.
- Support for Broadcom Brahma15 CPU cores.
- ARM assembly crypto updates from Ard Biesheuvel"

Change the behavior of omap2_dpll_round_rate() to round to either the
exact rate requested, or the next lowest rate that the clock is able to
provide.
This is not an ideal fix, but is intended to provide a relatively safe
way for drivers to set PLL rates, until a better solution can be
implemented.
For the time being, omap3_noncore_dpll_set_rate() is still allowed to
set its rate to something other than what the caller requested; but will
warn when this occurs.

DMA interrupts are now available in of, and the definitions are

interrupt resources for dma from devicetree.
Signed-off-by: Nishanth Menon <nm@ti.com>
Signed-off-by: Tony Lindgren <tony@atomide.com>
we have currently 2 DMA drivers that try to co-exist.
drivers/dma/omap-dma.c which registers it's own IRQ and is device tree
aware and uses arch/arm/plat-omap/dma.c instance created by
arch/arm/mach-omap2/dma.c to maintain channel usage (omap_request_dma).
Currently both try to register interrupts and mach-omap2/plat-omap dma.c
attempts to use the IRQ number registered by hwmod to register it's own
interrupt handler.
Now, there is no reasonable way of static allocating DMA irq in GIC
SPI when we use crossbar. However, since the dma_chan structure is
freed as a result of IRQ not being present due to devm allocation,
maintaining information of channel by platform code fails at a later
point in time when that region of memory is reused.
So, if hwmod does not indicate an IRQ number, then, assume that
dma-engine will take care of the interrupt handling.

ARMv6 and greater introduced a new instruction ("bx") which can be used
to return from function calls. Recent CPUs perform better when the
"bx lr" instruction is used rather than the "mov pc, lr" instruction,
and this sequence is strongly recommended to be used by the ARM
architecture manual (section A.4.1.1).
We provide a new macro "ret" with all its variants for the condition
code which will resolve to the appropriate instruction.
Rather than doing this piecemeal, and miss some instances, change all
the "mov pc" instances to use the new macro, with the exception of
the "movs" instruction and the kprobes code. This allows us to detect
the "mov pc, lr" case and fix it up - and also gives us the possibility
of deploying this for other registers depending on the CPU selection.

On OMAP SOCs using PL310 controllers, power_ctrl register is not
accessible from non-secure software even on PL310 versions which
support it. The secure code takes care of setting it up correctly
and power transitions are proven on these devices.
For example, AM437x has L2C-310 version r3p3 and ROM code on that
device does not support writing to L2C-310 power control register.
The L2C driver, however, tries writing to this register for all
revisions >= r3p0.
This leads to a warning dump on boot which leads most users to believe
that L2 cache is non-functional.
Since the problem is understood, and cannot be addressed through
software, replace the warning with a pr_info() while maintaining the
WARN_ON() for other truly unexpected scenarios.

created unconditionally whenever CONFIG_TIDSPBRIDGE is

This week's arm-soc fixes:
- A set of of OMAP patches that we had missed Tony's pull request of:
- Reset fix for am43xx
- Proper OPP table for omap5
- Fix for SoC detection of one of the DRA7 SoCs
- hwmod updates to get SATA and OCP to work on omap5 (drivers merged in 3.16)
- ... plus a handful of smaller fixes
- sunxi needed to re-add machine specific restart code that was removed in
anticipation of a watchdog driver being merged for 3.16, and it didn't make
it in.
- Marvell fixes for PCIe on SMP and a big-endian fix.
- A trivial defconfig update to make my capri test board boot with
bcm_defconfig again.
... and a couple of MAINTAINERS updates, one to claim new Keystone
drivers that have been merged, and one to merge MXS and i.MX (both
Freescale platforms).
The largest diffs come from the hwmod code for omap5 and the re-add of
the restart code on sunxi. The hwmod stuff is quite late at this point
but it slipped through cracks repeatedly while coming up the maintainer
chain and only affects the one SoC so risk is low.

A first set of bug fixes that didn't make it for the merge window, and
two Kconfig cleanups that still make sense at this point. Unfortunately,
one of the two cleanups caused an unintended change in the original
version, so we had to revert one part of it and do some more testing
to ensure the rest is really fine. There was also a last-minute
rebase of the patches to remove another bad commit.

A number of configurations spit out warnings similar to:
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)
Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
eventually get rid of CACHE_PL310, surround these errata options with an
if CACHE_L2X0 conditional rather than repeating the dependency against
each.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

Commit d941f86fad ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:
arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'
This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.
This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.

Fix a parser-bug in the omap2 muxing code where muxtable-entries will be
wrongly selected if the requested muxname is a *prefix* of their
m0-entry and they have a matching mN-entry. Fix by additionally checking
that the length of the m0_entry is equal.
For example muxing of "dss_data2.dss_data2" on omap32xx will fail
because the prefix "dss_data2" will match the mux-entries "dss_data2" as
well as "dss_data20", with the suffix "dss_data2" matching m0 (for
dss_data2) and m4 (for dss_data20). Thus both are recognized as signal
path candidates:
Relevant muxentries from mux34xx.c:
_OMAP3_MUXENTRY(DSS_DATA20, 90,
"dss_data20", NULL, "mcspi3_somi", "dss_data2",
"gpio_90", NULL, NULL, "safe_mode"),
_OMAP3_MUXENTRY(DSS_DATA2, 72,
"dss_data2", NULL, NULL, NULL,
"gpio_72", NULL, NULL, "safe_mode"),
This will result in a failure to mux the pin at all:
_omap_mux_get_by_name: Multiple signal paths (2) for dss_data2.dss_data2
Patch should apply to linus' latest master down to rather old linux-2.6
trees.

There's one OMAP SoC integration fix for the AM43xx SoC, without
which, IP blocks can't be placed into hard-reset.
There is also one OMAP5 SoC data addition patch that should have gone
in for v3.16. Normally I wouldn't send this as part of an -rc series,
since it's not technically a fix. But I'd like to make an exception in
this case because:
- it's intended to go in very early in the v3.16-rc series (or even
pre-rc1);
- it's a fairly small change;
- the impact is limited to a single SoC and a single device;
- the only reason that it didn't go in earlier is because it "slipped
through the cracks," rather than for any technical reason.

The majority of these changes are cleanups and fixes across all drivers.
Redundant error messages are removed and more PWM controllers set the
.can_sleep flag to signal that they can't be used in atomic context.
Support is added for the Broadcom Kona family of SoCs and the Intel LPSS
driver can now probe PCI devices in addition to ACPI devices. Upon shut-
down, the pwm-backlight driver will now power off the backlight. It also
uses the new descriptor-based GPIO API for more concise GPIO handling.
A large chunk of these changes also converts platforms to use the lookup
mechanism rather than relying on the global number space to reference
PWM devices. This is largely in preparation for more unification and
cleanups in future patches. Eventually it will allow the legacy PWM API
to be removed.

Duty Cycle Correction(DCC) needs to be enabled if the MPU is to run at
frequencies beyond 1.4GHz for OMAP5, DRA75x, DRA72x.
MPU DPLL has a limitation on the maximum frequency it can be locked
at. Duty Cycle Correction circuit is used to recover a correct duty
cycle for achieving higher frequencies (hardware internally switches
output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)).
For further information, See the note on OMAP5432 Technical Reference
Manual(SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters",
and also the "OMAP543x ES2.0 DM Operating Conditions Addendum v0.5"
chapter 2.1 "Micro Processor Unit (MPU)". Equivalent information is
present in relevant DRA75x, 72x documentation(SPRUHP2E, SPRUHI2P).

Pull ARM updates from Russell King:
- Major clean-up of the L2 cache support code. The existing mess was
becoming rather unmaintainable through all the additions that others
have done over time. This turns it into a much nicer structure, and
implements a few performance improvements as well.
- Clean up some of the CP15 control register tweaks for alignment
support, moving some code and data into alignment.c
- DMA properties for ARM, from Santosh and reviewed by DT people. This
adds DT properties to specify bus translations we can't discover
automatically, and to indicate whether devices are coherent.
- Hibernation support for ARM
- Make ftrace work with read-only text in modules
- add suspend support for PJ4B CPUs
- rework interrupt masking for undefined instruction handling, which
allows us to enable interrupts earlier in the handling of these
exceptions.
- support for big endian page tables
- fix stacktrace support to exclude stacktrace functions from the
trace, and add save_stack_trace_regs() implementation so that kprobes
can record stack traces.
- Add support for the Cortex-A17 CPU.
- Remove last vestiges of ARM710 support.
- Removal of ARM "meminfo" structure, finally converting us solely to
memblock to handle the early memory initialisation.

Here is the big USB driver pull request for 3.16-rc1.
Nothing huge here, but lots of little things in the USB core, and in
lots of drivers. Hopefully the USB power management will be work better
now that it has been reworked to do per-port power control dynamically.
There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
is finally gone now that everything has been converted over to the
dynamic debug inteface, the last hold-out drivers were cleaned up and
the config option removed. There were also other minor things all
through the drivers/usb/ tree, the shortlog shows this pretty well.
All have been in linux-next, including the very last patch, which came
from linux-next to fix a build issue on some platforms.

- Qualcomm APQ8064 and APQ8084 SoCs and eval boards
- Nvidia Jetson TK1 development board (Tegra T124-based)

The bulk of this branch is updates for Renesas Shmobile. They are still
doing some enablement for classic boards first, and then come up with DT
bindings when they've had a chance to learn more about the hardware. Not
necessarily a bad way to go about it, and they're looking at moving some
of the temporary board code resulting from it to drivers/staging instead
to avoid the churn here.
As a result of the shmobile clock cleanups, we end up merging quite a
bit of SH code here as well. We ended up merging it here instead of in
the cleanup branch due to the other board changes depending on it.

L2 cache initialization for OMAP4 redundantly sets the cache policy to

Avoid reading directly from the L2 registers in platform code. The L2
code will have already saved the register values itself into the
l2x0_saved_regs structure, so platform code should just move these
values to where they're required.
This is safe because the L2x0 will have been initialised by an early
initcall, whereas the OMAP4 PM code is initialised late.

Since we now always enable NS access to the unlock registers, this can
be removed from OMAP4. Remove the NS access bit for the interrupt
registers from OMAP4 as well - nothing in the kernel accesses that yet,
and we can add it in core code when we have the need.

The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP. Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to

this.

Move the panel/encoder driver compatible-string converter from

In omap2_common_pm_late_init suspend_set_ops was called to set common
suspend handling functions for all omap platforms. This created two
problems. First, these suspend ops were being set for all platforms,
regardless of whether or not suspend support has been integrated so in
the case of AM33XX, suspend to mem was presented as available but
failed every time. Second, some platforms will need to define a
completely separate set of suspend ops, such as AM33XX, due to
differences from previous omap platforms so there is no need to
always set the common omap ops.
This patch moves the suspend_set_ops call from omap2_common_pm_late_init
into a separate function that then gets called in the omap*_pm_init
functions for each platform.

On OMAP4 panda board, there have been several bug reports about boot
hang and lock-ups with CPU_IDLE enabled. The root cause of the issue
is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 :
use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common
code for right reasons but on OMAP4 which suffers from a nasty ROM code
bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..},
we loose interrupts which leads to issues like lock-up, hangs etc.
Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP
flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to
avoid the issue. With this change, OMAP4 panda boards, the mentioned
issues are getting fixed. We no longer loose interrupts which was the cause
of the regression.

Currently we're attempting to use a static value for the
voltctrl register that only works for controlling the PMIC
over I2C4. For using sys_off_mode signaling, we need to update
update clksetup, voltsetup1, voltsetup2 and voltctrl registers
dynamically depending on the idle state.
So let's fix this by configuring things for I2C4 controlled idle
and sys_off_mode pin controlled idle, and then write the
configured register values depending on the idle state. This
is similar what N900 kernel is doing too.

Commit c589eb3869 (ARM: OMAP3: VC: calculate ramp times)
started using regulator slew rates for calculating the idle
mode start-up times. This works fine for I2C4 controlled
regulator scaling as the regulators are never completely
turned off.
For sys_off_mode pin controlled PMIC scripts, the slew rate
based calculations won't work at all as the regulators are
completely turned off and the start-up time is much longer.
This means currently omap3_set_off_timings currently has
zero chance of working on any real hardare. The current code
is broken in at least the following ways:
1. It attempts to use the default ULONG_MAX value for the
oscillator start-up value as we're currently never
initializing the start-up value.
2. It relies on a magic number potentially set by the
bootloader for volsetup2 register.
3. If no magic value is passed, it attempts to calculate
voltsetup2 register based on the regulator slew rate.
This won't work as there is roughly at least five
times the delay needed for turning on vdd1 and vdd2
regulators.
4. It does duplicate register write to OMAP3_PRM_VOLTOFFSET
5. It duplicates the code for omap_usec_to_32k unnecessarily
6. It initialized global registers twice, once for each channel
Let's just remove the broken code and call omap3_set_i2c_timings
directly, we're better off with this function doing nothing until
it's fixed. And otherwise further fixes to omap3_set_off_timings
will be unreadable.
And let's get rid of omap3_set_clksetup as that's not needed
for off-idle controlled by I2C4 as in that case the oscillator
is never shut down.

While debugging legacy mode vs device tree booted PM regressions,
I noticed that omap3 is not toggling sys_clkreq and sys_off_mode
pins like it should.
The sys_clkreq and sys_off_mode pins are not toggling because of
the following issues:
1. The default polarity for the sys_off_mode pin is wrong.
OFFMODE_POL needs to be cleared for sys_off_mode to go down when
hitting off-idle, while CLKREQ_POL needs to be set so sys_clkreq
goes down when hitting retention.
2. The values for voltctrl register need to be updated dynamically.
We need to set either the retention idle bits, or off idle bits
in the voltctrl register depending the idle mode we're targeting
to hit.
Let's fix these two issues as otherwise the system will just
hang if any twl4030 PMIC idle scripts are loaded. The only case
where the system does not hang is if only retention idle over I2C4
is configured by the bootloader.
Note that even without the twl4030 PMIC scripts, these fixes will
do the proper signaling of sys_clkreq and sys_off_mode pins, so
the fixes are needed to fix monitoring of PM states with LEDs or
an oscilloscope.

On my DRA7 system, when the kernel is built in Thumb-2 mode, the secondary CPU
(Cortex A15) fails to come up causing SMP boot on second CPU to timeout. This
seems to be because the CPU is in ARM mode once the ROM hands over control to
the kernel. Switch to Thumb-2 mode if required once the kernel is control of
secondary CPU. On OMAP4 on the other hand, it appears to be in Thumb-2 mode on
entry so this is not required and SMP boot works as is.
Also corrected a spurious '+' and updated copyright information.

At least the smc91x driver expects the device to be at 0x300
offset from bus base address. This does not work currently
for GPMC when booted in device tree mode as it attempts to
remap the the allocated GPMC partition to the address
configured by the device tree plus the device offset.
Note that this works just fine when booted with legacy mode.
Let's fix the issue by just ignoring any device specific
offset while remapping. And let's make sure the remap
address confirms to the GPMC 16MB minimum granularity
as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits.
Otherwise we can get something like this:

I noticed a regression where the omap sys_clkreq signal will never
trigger for omap3 when booted with device tree while it triggers
when booted in legacy mode. This means voltage scaling does not
do anything when booted with device tree.
Turns out the reason is we fail to initialize the SmartReflex
enable bit in twl4030 with the following error:
twl: not initialized
And that happens because we are wrongly tinkering with the twl4030
registers in arch/arm/mach-omap2/omap_twl.c before the driver is
initialized. Looking at the the SmartReflex bit enable code in
omap_twl.c, we need to always set it.
So let's fix the issue by always enabling the twl4030 SmartReflex
bit in the drivers/mfd/twl-core.c probe, and drop the related
code in omap_twl.c.
Note that we still have some twl4030 tinkering left in omap_twl.c
for the twl6030 case, but that's a different patch.

However v1 apparently seemed to have been pulled in by mistake
introducing the bug.
Given of_find_property() does return NULL when the node passed is

On AM43xx, if a PLL is in bypass at kernel init, the code in
omap2_get_dpll_rate() will not realize this and will try to calculate
the clock rate using the multiplier and the divider, resulting in
errors.
omap2_init_dpll_parent() has similar issue.
Add the missing soc_is_am43xx() check to make the code work on AM43xx.

There is a solitary write to this register every wakeup from off-mode,
which isn't doing anything, so remove it.
Also note that modifying this register trashes any attempted
voltage scaling configuration and the change probably should
never have gotten merged in the first place.

that, reset controllers for STi as well as a large rework of the

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann:
"These cleanup patches are mainly move stuff around and should all be
harmless. They are mainly split out so that other branches can be
based on top to avoid conflicts.
Notable changes are:
- We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used (Uwe Kleine-König)
- The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions (Kumar Gala)
- A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
- Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
- mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
- at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people)"

...
Lots of isolated bug fixes that were not found to be important
enough to be submitted before the merge window or backported
into stable kernels.
The vast majority of these came out of Arnd's randconfig testing
and just prevents running into build-time bugs in configurations
that we do not care about in practice.

Pull ARM changes from Russell King:
- Perf updates from Will Deacon:
- Support for Qualcomm Krait processors (run perf on your phone!)
- Support for Cortex-A12 (run perf stat on your FPGA!)
- Support for perf_sample_event_took, allowing us to automatically decrease
the sample rate if we can't handle the PMU interrupts quickly enough
(run perf record on your FPGA!).
- Basic uprobes support from David Long:
This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
- ARMv7M (microcontroller) updates from Uwe Kleine-König
- OMAP DMA updates (recently added Vinod's Ack even though they've been
sitting in linux-next for a few months) to reduce the reliance of
omap-dma on the code in arch/arm.
- SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan
- Support for Cortex-A12 CPU
- Align support for ARMv6 with ARMv7 so they can cooperate better in a
single zImage.
- Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support.
- Removal of IRQ_DISABLED from various ARM files
- Improved efficiency of virt_to_page() for single zImage
- Patch from Ulf Hansson to permit runtime PM callbacks to be available for
AMBA devices for suspend/resume as well.
- Finally kill asm/system.h on ARM.
