a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc() 
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

6da2ec5605 treewide: kmalloc() -> kmalloc_array() 
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

        kmalloc(a * b, gfp)

with:
        kmalloc_array(a * b, gfp)

as well as handling cases of:

        kmalloc(a * b * c, gfp)

This does, however, attempt to ignore constant size factors like:

        kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Linus Torvalds
6419945e33 This time we have a good set of changes to the core framework that do some 
general cleanups, but nothing too major. The majority of the diff goes to
 two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for
 Actions Semi so it takes up some lines to add all the different types, and
 the Qualcomm diff is there because we add support for two SoCs and it's quite
 a bit of data.
 
 Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And
 then the long tail of driver updates for various fixes and stuff follows
 after that.
 
 Core:
  - debugfs cleanups removing error checking and an unused provider API
  - Removal of a clk init typedef that isn't used
  - Usage of match_string() to simplify parent string name matching
  - OF clk helpers moved to their own file (linux/of_clk.h)
  - Make clk warnings more readable across kernel versions
 
 New Drivers:
  - Qualcomm SDM845 GCC and Video clk controllers
  - Qualcomm MSM8998 GCC
  - Actions Semi S900 SoC support
  - Nuvoton npcm750 microcontroller clks
  - Amlogic axg AO clock controller
 
 Removed Drivers:
  - Deprecated Rockchip clk-gate driver
 
 Updates:
  - debugfs functions stopped checking return values
  - Support for the MSIOF module clocks on Rensas R-Car M3-N
  - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
  - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
  - Berlin and Amlogic SPDX tagging
  - Usage of of_clk_get_parent_count() in more places
  - Proper implementation of the CDEV1/2 clocks on Tegra20
  - Allwinner H6 PRCM clock support and R40 EMAC support
  - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet
  - Round closest support for meson's mpll driver
  - Support for meson8b nand clocks and gxbb video decoder clocks
  - Mediatek mali clks
  - STM32MP1 fixes
  - Uniphier LD11/LD20 stream demux system clock

Pull overflow updates from Kees Cook:
 "This adds the new overflow checking helpers and adds them to the
  2-factor argument allocators. And this adds the saturating size
  helpers and does a treewide replacement for the struct_size() usage.
  Additionally this adds the overflow testing modules to make sure
  everything works.

  I'm still working on the treewide replacements for allocators with
  "simple" multiplied arguments:

     *alloc(a * b, ...) -> *alloc_array(a, b, ...)

  and

     *zalloc(a * b, ...) -> *calloc(a, b, ...)

  as well as the more complex cases, but that's separable from this
  portion of the series. I expect to have the rest sent before -rc1
  closes; there are a lot of messy cases to clean up.

   - Introduce arithmetic overflow test helper functions (Rasmus)

   - Use overflow helpers in 2-factor allocators (Kees, Rasmus)

MIPS: lantiq: gphy: Drop reboot/remove reset asserts 
While doing a global software reset, these bits are not cleared and let
some bootloader fail to initialise the GPHYs. The bootloader don't
expect the GPHYs in reset, as they aren't during power on.

The asserts were a workaround for a wrong syscon-reboot mask. With a
mask set which includes the GPHY resets, these resets aren't required
any more.

a2dd6877b4 soc: ti: K2G: provide APIs to support driver probe deferral 
This patch provide APIs to allow client drivers to support
probe deferral. On K2G SoC, devices can be probed only
after the ti_sci_pm_domains driver is probed and ready.
As drivers may get probed at different order, any driver
that depends on knav dma and qmss drivers, for example
netcp network driver, needs to defer probe until
knav devices are probed and ready to service. To do this,
add an API to query the device ready status from the knav
dma and qmss devices.

350601b4f7 soc: ti: K2G: enhancement to support QMSS in K2G NAVSS 
Navigator Subsystem (NAVSS) available on K2G SoC has a cut down
version of QMSS with less number of queues, internal linking ram
with lesser number of buffers etc.  It doesn't have status and
explicit push register space as in QMSS available on other K2 SoCs.
So define reg indices specific to QMSS on K2G. This patch introduces
"ti,66ak2g-navss-qm" compatibility to identify QMSS on K2G NAVSS
and to customize the dts handling code. Per Device manual,
descriptors with index less than or equal to regions0_size is in region 0
in the case of K2 QMSS where as for QMSS on K2G, descriptors with index
less than regions0_size is in region 0. So update the size accordingly in
the regions0_size bits of the linking ram size 0 register.

ca4e7c5120 The large diff this time around is from the addition of a new clk driver 
for the TI Davinci family of SoCs. So far those clks have been supported
 with a custom implementation of the clk API in the arch port instead of in
 the CCF. With this driver merged we're one step closer to having a single
 clk API implementation.
 
 The other large diff is from the Amlogic clk driver that underwent some
 major surgery to use regmap. Beyond that, the biggest hitter is Samsung
 which needed some reworks to properly handle clk provider power domains
 and a bunch of PLL rate updates.
 
 The core framework was fairly quiet this round, just getting some cleanups
 and small fixes for some of the more esoteric features. And the usual
 set of driver non-critical fixes, cleanups, and minor additions are here as
 well.
 
 Core:
  - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
  - debugfs ops macroized to shave some lines of boilerplate code
  - Always calculate the phase instead of caching it in clk_get_phase()
  - More __must_check on bulk clk APIs
 
 New Drivers:
  - TI's Davinci family of SoCs
  - Intel's Stratix10 SoC
  - stm32mp157 SoC
  - Allwinner H6 CCU
  - Silicon Labs SI544 clock generator chip
  - Renesas R-Car M3-N and V3H SoCs
  - i.MX6SLL SoCs
 
 Removed Drivers:

 Updates:
  - Mediatek MT2701 and MT7622 audsys support and MT2712 updates
  - STM32F469 DSI and STM32F769 sdmmc2 support
  - GPIO clks can sleep now
  - Spreadtrum SC9860 RTC clks
  - Nvidia Tegra MBIST workarounds and various minor fixes
  - Rockchip phase handling fixes and a memory leak plugged

38c23685b2 ARM: SoC driver updates for 4.17 
The main addition this time around is the new ARM "SCMI" framework,
 which is the latest in a series of standards coming from ARM to do power
 management in a platform independent way. This has been through many
 review cycles, and it relies on a rather interesting way of using the
 mailbox subsystem, but in the end I agreed that Sudeep's version was
 the best we could do after all.
 
 Other changes include:
 
 - the ARM CCN driver is moved out of drivers/bus into drivers/perf,
   which makes more sense. Similarly, the performance monitoring
   portion of the CCI driver are moved the same way and cleaned up
   a little more.
 
 - a series of updates to the SCPI framework
 
 - support for the Mediatek mt7623a SoC in drivers/soc
 
 - support for additional NVIDIA Tegra hardware in drivers/soc
 
 - a new reset driver for Socionext Uniphier
 
 - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
   drivers/firmware and drivers/reset across platforms

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "The main addition this time around is the new ARM "SCMI" framework,
  which is the latest in a series of standards coming from ARM to do
  power management in a platform independent way.

  This has been through many review cycles, and it relies on a rather
  interesting way of using the mailbox subsystem, but in the end I
  agreed that Sudeep's version was the best we could do after all.

  Other changes include:

   - the ARM CCN driver is moved out of drivers/bus into drivers/perf,
     which makes more sense. Similarly, the performance monitoring
     portion of the CCI driver are moved the same way and cleaned up a
     little more.

   - a series of updates to the SCPI framework

   - support for the Mediatek mt7623a SoC in drivers/soc

   - support for additional NVIDIA Tegra hardware in drivers/soc

   - a new reset driver for Socionext Uniphier

   - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
     drivers/firmware and drivers/reset across platforms"

167569343f ARM: SoC platform updates for 4.17 
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

b240b419db ARM: SoC device tree updates for 4.17 
This is the usual set of changes for device trees, with over 700
 non-merged changesets. There is an ongoing set of dtc warning fixes and
 the usual bugfixes, cleanups and added device support.
 
 The most interesting bit as usual is support for new machines listed
 below:
 
 - The Allwinner H6 makes its debut with the Pine-H64 board, and we get
   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server
 
 - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
   msm8974 based Galaxy S5 is a rather different phone made by the same
   company.
 
 - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
   for the various boards made by Xilinx themselves, as well as the
   Digilent Zybo Z7.
 
 - The ARM Versatile family now supports the "IB2" interface board.
 
 - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
   evaluation boards named after a kind of beer, as most of them are.
   The r8a77980 (V3H) based "Condor" apparently doesn't follow that
   tradition. ;-)
 
 - ROC-RK3328-CC is a simple developement board from the Libre Computer
   Project, based on the Rockchips RK3328 SoC
 
 - Haiku is another development board plus Qseven module based on Rockchips
   RK3368 and made by Theobroma Systems.

59162c9366 Renesas ARM Based SoC Updates for v4.17 
01d675f159 ARM: shmobile: rcar-gen2: Add watchdog support
 58adf1ba0d ARM: shmobile: Add watchdog support
 
 * SoC
   - Identify R-Car V3H (r8a77980) and M3N (r8a77965)
 
   - Enable R-Car Gen2 regulator quirk for Stout board with H3 (r8a7790) SoC
 
     Marek Vaust says "Regulator setup is suboptimal on H2 Stout too. The
     Stout newly has two DA9210 regulators, so the quirk is extended to
     handle another DA9210 at i2c address 0x70."
 
   - Add watchdog support
 
     This is the SoC portion of the following solution. It is not yet
     enabled in DT as it is not functional without clock dependencies
     in place.
 
     Fabrizio Castro says "this series has been around for some time as RFC,
     and it has collected useful comments from the community along the way.
     The solution proposed by this patch set works for most R-Car Gen2 and
     RZ/G1 devices, but not all of them. We now know that for some R-Car
     Gen2 early revisions there is no proper software fix. Anyway, no
     product has been built around early revisions, but development boards
     mounting early revisions (basically prototypes) are still out there.
     As a result, this series isn't enabling the internal watchdog on R-Car
     Gen2 boards, developers may enable it in board specific device trees if
     needed.  This series has been tested by me on the iwg20d, iwg22d,
     Lager, Alt, and Koelsch boards.
 
    The problem
    ===========
    To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to
    ICRAM1 and we program the [S]BAR registers so that when we turn ON the
    non-boot CPUs they are redirected to the reset vector installed by Linux
    in ICRAM1, and eventually they continue the execution to RAM, where the
    SMP bring-up code will take care of the rest.  The content of the [S]BAR
    registers survives a watchdog triggered reset, and as such after the
    watchdog fires the boot core will try and execute the SMP bring-up code
    instead of jumping to the bootrom code.
 
    The fix
    =======
    The main strategy for the solution is to let the reset vector decide if
    it needs to jump to shmobile_boot_fn or to the bootrom code.  In a
    watchdog triggered reset scenario, since the [S]BAR registers keep their
    values, the boot CPU will jump into the newly designed reset vector, the
    assembly routine will eventually test WOVF (a bit in register RWTCSRA
    that indicates if the watchdog counter has overflown, the value of this
    bit gets retained in this scenario), and jump to the bootrom code which
    will in turn load up the bootloader, etc.  When bringing up SMP or using
    CPU hotplug, the reset vector will jump to shmobile_boot_fn instead."
 
 * R-Car Rst
   - Add support for R-Car V3H (r8a77980) and V3H (r8a77980)
 
 * R-Car SYSC
   - Mark rcar_sysc_matches[] __initconst
 
    Geert Uytterhoeven says "This frees another 1764 bytes
    (arm32/shmobile_defconfig) or 1000 bytes (arm64/renesas_defconfig) of
    memory after kernel init."
 
   - Fix power area parents
 
     Sergei Shtylyov says "According to the figure 9.2(b) of the R-Car
     Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and
     A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the
     SYSC driver has those parents wrong.."

03fe2debbb Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 
Fun set of conflict resolutions here...

For the mac80211 stuff, these were fortunately just parallel
adds.  Trivially resolved.

In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.

In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.

The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.

The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:

====================

    Due to bug fixes found by the syzkaller bot and taken into the for-rc
    branch after development for the 4.17 merge window had already started
    being taken into the for-next branch, there were fairly non-trivial
    merge issues that would need to be resolved between the for-rc branch
    and the for-next branch.  This merge resolves those conflicts and
    provides a unified base upon which ongoing development for 4.17 can
    be based.

    Conflicts:
            drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
            (IB/mlx5: Fix cleanup order on unload) added to for-rc and
            commit b5ca15ad7e (IB/mlx5: Add proper representors support)
            add as part of the devel cycle both needed to modify the
            init/de-init functions used by mlx5.  To support the new
            representors, the new functions added by the cleanup patch
            needed to be made non-static, and the init/de-init list
            added by the representors patch needed to be modified to
            match the init/de-init list changes made by the cleanup
            patch.
    Updates:
            drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
            prototypes added by representors patch to reflect new function
            names as changed by cleanup patch
            drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
            stage list to match new order from cleanup patch

c932ba8c38 soc: mediatek: add SCPSYS power domain driver for MediaTek MT7623A SoC 
Add SCPSYS power domain driver for MT7623A SoC. The MT7623A's power
domains are the subset of MT7623 SoC's ones. As MT7623 SoC has full
features whereas MT7623A is being designed just for router applications.
Thus, MT7623A doesn't include those power domains multimedia function
belongs to. In order to avoid certain errors undoubtedly happening at
registering those power domains on MT7623A SoC using the existing MT7623
SCPSYS driver, it's required to define another setup specifically for
MT7623A SoC.

90c29ed762 soc: qcom: wcnss_ctrl: Fix increment in NV upload 
hdr.len includes both the size of the header and the fragment, so using
this when stepping through the firmware causes us to skip 16 bytes every
chunk of 3072 bytes; causing only the first fragment to actually be
valid data.

Instead use fragment size steps through the firmware blob.

fa65f80451 soc: qcom: rmtfs-mem: Add support for assigning memory to remote 
On some platform the remote processor's memory map is not statically
configured in TrustZone, so each memory region that is to be accessed by
the remote needs a call into TrustZone to set up the remote's
permissions.

Implement this for the rmtfs memory driver, to give the modem on 8996
access to the shared file system buffers.

tegra_powergate_sequence_power_up() makes up a struct tegra_powergate
from scratch in order to reuse the same code as used by the generic PM
domain implementation. However, subsequent patches will need to access
the struct tegra_pmc * embedded in the powergate structure, so we need
to make sure we always pass it in.
