The pm-rmobile driver is really a driver for the System Controller
(SYSC) found in R-Mobile SoCs.  An equivalent driver for R-Car SoCs is
already located under drivers/soc/renesas/.

Hence move the pm-rmobile driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and rename it to rmobile-sysc.

Enable compile-testing on non-ARM and non-R-Mobile SoCs.

Merge tag 'tags/bcm2835-drivers-next-2018-11-27' into drivers/next

This pull request adds SPDX to BCM2835 drivers, and fixes some bugs in
the firmware driver (silently hanging if the VPU doesn't respond to a
mailbox transaction, and undersized buffers in the firmware property
transactions for tags that aren't used yet in the upstream).

arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for
Renesas SoCs, while other vendors have only a single Kconfig symbol.

Increase consistency with other vendors by moving the SoC-specific
Kconfig symbols to drivers/soc/renesas/Kconfig.

Increase consistency with R-Car Gen1 and Gen2 SoCs on arm32 by
introducing a family-specific Kconfig symbol for R-Car Gen3
(ARCH_RCAR_GEN3), which enables family-specific hardware features.
While so far only a single family (R-Car Gen3 and derivatives) of
Renesas arm64 SoCs is supported by Linux, this will make it easier
to add support for other SoC families later.

Let's change the function signature to return the pointer to memory or
an error pointer on failure, and take an argument that lets us return
the size of the aux data read. This way we can remove the
cmd_db_read_aux_data_len() API entirely and also get rid of the memcpy
operation from cmd_db to the caller. Updating the only user of this code
shows that making this change allows us to remove a function and put the
lookup where the user is.

The cmd_db_get_header() function is a static local function that doesn't
need to copy anything from one place to another. Instead, it can just
point into the region by returning pointers to what we're looking for.
If we do that, we should mark what we're returning as const so that code

where cpu_map is a local variable. As we leave the function, this
will point to nowhere-land, and things will end-up badly.

Instead, let's use a proper cpumask that gets allocated, giving

as well as have a hypothetical 64bit future.

Linus Torvalds b22b6beae6 ARM: SoC driver updates for 4.17

 - The TEE subsystem gains an in-kernel interface to access the TEE
   from device drivers.
 
 - The reset controller subsystem gains a driver for the Qualcomm
   Snapdragon 845 Power Domain Controller.
 
 - The Xilinx Zynq platform now has a firmware interface for its
   platform management unit. This contains a firmware "ioctl" interface
   that was a little controversial at first, but the version we merged
   solved that by not exposing arbitrary firmware calls to user space.
 
 - The Amlogic Meson platform gains a "canvas" driver that is used
   for video processing and shared between different high-level drivers.
 
 The rest is more of the usual, mostly related to SoC specific power
 management support and core drivers in drivers/soc:
 
 - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
   features related to power and reset control.
 
 - The Mediatek mt8183 and mt6765 SoC platforms gain support for
   their respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

Linus Torvalds 685f7e4f16 powerpc updates for 4.20
Notable changes:
 
  - A large series to rewrite our SLB miss handling, replacing a lot of fairly
    complicated asm with much fewer lines of C.
 
  - Following on from that, we now maintain a cache of SLB entries for each
    process and preload them on context switch. Leading to a 27% speedup for our
    context switch benchmark on Power9.
 
  - Improvements to our handling of SLB multi-hit errors. We now print more debug
    information when they occur, and try to continue running by flushing the SLB
    and reloading, rather than treating them as fatal.
 
  - Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
 
  - Add support for physical memory up to 2PB in the linear mapping on 64-bit
    Book3S. We only support up to 512TB as regular system memory, otherwise the
    percpu allocator runs out of vmalloc space.
 
  - Add stack protector support for 32 and 64-bit, with a per-task canary.
 
  - Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
 
  - Support recognising "big cores" on Power9, where two SMT4 cores are presented
    to us as a single SMT8 core.
 
  - A large series to cleanup some of our ioremap handling and PTE flags.
 
  - Add a driver for the PAPR SCM (storage class memory) interface, allowing
    guests to operate on SCM devices (acked by Dan).
 
  - Changes to our ftrace code to handle very large kernels, where we need to use
    a trampoline to get to ftrace_caller().
 
 Many other smaller enhancements and cleanups.

Merge tag 'powerpc-4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:
 "Notable changes:

   - A large series to rewrite our SLB miss handling, replacing a lot of
     fairly complicated asm with much fewer lines of C.

   - Following on from that, we now maintain a cache of SLB entries for
     each process and preload them on context switch. Leading to a 27%
     speedup for our context switch benchmark on Power9.

   - Improvements to our handling of SLB multi-hit errors. We now print
     more debug information when they occur, and try to continue running
     by flushing the SLB and reloading, rather than treating them as
     fatal.

   - Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).

   - Add support for physical memory up to 2PB in the linear mapping on
     64-bit Book3S. We only support up to 512TB as regular system
     memory, otherwise the percpu allocator runs out of vmalloc space.

   - Add stack protector support for 32 and 64-bit, with a per-task
     canary.

   - Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.

   - Support recognising "big cores" on Power9, where two SMT4 cores are
     presented to us as a single SMT8 core.

   - A large series to cleanup some of our ioremap handling and PTE
     flags.

   - Add a driver for the PAPR SCM (storage class memory) interface,
     allowing guests to operate on SCM devices (acked by Dan).

   - Changes to our ftrace code to handle very large kernels, where we
     need to use a trampoline to get to ftrace_caller().

  And many other smaller enhancements and cleanups.

Linus Torvalds a978a5b8d8 net/kconfig: Make QCOM_QMI_HELPERS available when COMPILE_TEST
The networking merge brought in the experimental support for the
Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
dependency.

But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.

As a result, a "make allmodconfig" complains

  WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS
    Depends on [n]: ARCH_QCOM && NET [=y]
    Selected by [m]:
    - ATH10K_SNOC [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && ATH10K [=m] && (ARCH_QCOM || COMPILE_TEST [=y])

Fix the config-time warning by making QCOM_QMI_HELPERS available when
COMPILE_TEST, since the result seems to build fine.

Arnd Bergmann 9620135fe1 i.MX drivers update for 4.20:
- A couple of patches from Anson to update variable and macro naming
    in GPCv2 driver, as a preparation of reusing the driver on i.MX8.
  - Switch GPC/GPCv2 drivers to use SPDX identifier for licence claiming.
  - Clean up the unnecessary DT node name NULL pointer checking from
    imx-weim driver, since it can never be NULL at all.
  - A couple of improvements on GPC driver from Sven Schmitt to correct
    PDN register and use GPC_PGC_DOMAIN_* indexes for consistency.

patch renames all functions and structure definitions started

Add a couple of new APIs to check the probing status of qman and bman:
 'int bman_is_probed()' and 'int qman_is_probed()'.
They return the following values.
 *  1 if qman/bman were probed correctly
 *  0 if qman/bman were not yet probed
 * -1 if probing of qman/bman failed
Drivers that use qman/bman driver services are required to use these
APIs before calling any functions exported by qman or bman drivers
or otherwise they will crash the kernel.
The APIs will be used in the following couple of qbman portal patches
and later in the series in the dpaa1 ethernet driver.

Douglas Anderson 969fc78c37 soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples
The geni_se_clk_freq_match() has some strange semantics.  Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then

...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.

The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way.  ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

Douglas Anderson abc1c94471 soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()
The function clk_round_rate() is defined to return a "long", not an
"unsigned long".  That's because it might return a negative error
code.  Change the call in geni_se_clk_tbl_get() to check for errors.

While we're at it, get rid of a useless init of "freq".

NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable.  Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

Create a new function qcom_smem_partition_header() to encapsulate
validating locating a partition header and validating information

it more obvious how the common function is replacing duplicated code
elsewhere.  Initially it just verifies the header has the right

Alex Elder abc006b7a6 soc: qcom: smem: require order of host ids to match
In qcom_smem_enumerate_partitions(), we find all partitions that
have a given local host id in either its host0 or its host1 field
in the partition table entry.  We then verify that the header
structure at the start of each partition also contains the same two
host ids as is found in the table of contents.

There is no requirement that the order of the two host ids be the
same in the table of contents and in the partition header.

This patch changes that, requiring host0 to in the partition table
entry to equal host0 in the partition header structure (and similar
for the host1 values).

The global partition is indicated by having both host values in its

In qcom_smem_set_global_partition(), we check whether the header
structure at the beginning of the partition contains that host
value, but the check only verifies *one* of them.  Change the check
so the partition header must have SMEM_GLOBAL_HOST for *both* its

In qcom_smem_enumerate_partitions(), any partition table entry
having a zero offset or size field is ignored.  Move those checks
earlier in the loop, because there's no sense in examining the
host fields for those entries.

Add the same checks in qcom_smem_set_global_partition(), so the

This allows a later check for zero size or offset once the global

Douglas Anderson 867d4aa701 soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples
The geni_se_clk_freq_match() has some strange semantics.  Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then

...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.

The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way.  ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

Douglas Anderson e11bbcedec soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()
The function clk_round_rate() is defined to return a "long", not an
"unsigned long".  That's because it might return a negative error
code.  Change the call in geni_se_clk_tbl_get() to check for errors.

While we're at it, get rid of a useless init of "freq".

NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable.  Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

Johan Hovold 1dc6bd5e39 soc/tegra: pmc: Fix child-node lookup
Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.

To make things worse, the parent pmc node could end up being prematurely
freed as of_find_node_by_name() drops a reference to its first argument.

Linus Torvalds 2f34a64aea ARM: Device-tree updates
Business as usual -- the bulk of our changes are to devicetree files
 with new hardware support, new SoCs and platforms, and new board types.
 
 New SoCs/platforms:
  - Raspberry Pi Compute Module (CM1) and IO board
  - i.MX6SSL from NXP
  - Renesas RZ/N1D SoC (R9A06G032), Dual Cortex-A7 with Ethernet, CAN and
    PLC interfaces
  - TI AM654 SoC, Quad Cortex-A53, safety subsystem with Cortex-R5
    controllers, communication and PRU subsystem and lots of other
    interfaces (PCIe, USB3, etc).
 
 New boards and systems:
  - Several Atmel at91-based boards from Laird
  - Marvell Armada388-based Helios4 board from SolidRun
  - Samsung Aires-based phones (s5pv210)
  - Allwinner A64-based Pinebook laptop
 
 In addition to the above, there's the usual amount of new devices
 described on existing platforms, fixes and tweaks and new minor variants
 of boards/platforms.

     the ARM cpuidle driver (Sudeep Holla).

   - Add a new device links flag to the driver core to make links go
     away automatically on supplier driver removal (Vivek Gautam).

   - Eliminate potential race condition between system-wide power
     management transitions and system shutdown (Pingfan Liu).

   - Add a quirk to save NVS memory on system suspend for the ASUS 1025C
     laptop (Willy Tarreau).

   - Make more systems use suspend-to-idle (instead of ACPI S3) by
     default (Tristian Celestin).

   - Get rid of stack VLA usage in the low-level hibernation code on
     64-bit x86 (Kees Cook).

   - Fix error handling in the hibernation core and mark an expected
     fall-through switch in it (Chengguang Xu, Gustavo Silva).

   - Extend the generic power domains (genpd) framework to support
     attaching a device to a power domain by name (Ulf Hansson).

   - Fix device reference counting and user limits initialization in the
     devfreq core (Arvind Yadav, Matthias Kaehlcke).

   - Fix a few issues in the rk3399_dmc devfreq driver and improve its
     documentation (Enric Balletbo i Serra, Lin Huang, Nick Milner).

   - Drop a redundant error message from the exynos-ppmu devfreq driver
     (Markus Elfring)"
