487b1b32e3 reset: eyeq: add platform driver
Add Mobileye EyeQ reset controller driver, for EyeQ5, EyeQ6L and EyeQ6H
SoCs. Instances belong to a shared register region called OLB and gets
spawned as auxiliary device to the platform driver for clock.

There is one OLB instance for EyeQ5 and EyeQ6L. There are seven OLB
instances on EyeQ6H; three have a reset controller embedded:
 - West and east get handled by the same compatible.
 - Acc (accelerator) is another one.

Each instance vary in the number and types of reset domains.
Instances with single domain expect a single cell, others two.

b062ef2907 reset: reset-meson: Add support for Amlogic T7 SoC reset controller
There are 7 sets of Reset Source in Amlogic T7 SoC reset controller,
and the offset between base and level registers is 0x40.
Add a new compatible string and struct meson_reset_param to support
the reset controller on T7 SoC.

a05f87270e reset: core: add get_device()/put_device on rcdev
Since the rcdev structure is allocated by the reset controller drivers
themselves, they need to exists as long as there is a consumer. A call to
module_get() is already existing but that does not work when using
device-tree overlays. In order to guarantee that the underlying reset
controller device does not vanish while using it, add a get_device() call
when retrieving a reset control from a reset controller device and a
put_device() when releasing that control.

c2a96b7f18 Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
 
 Lots of stuff in here, with not a huge diffstat, but apis are evolving
 which required lots of files to be touched.  Highlights of the changes
 in here are:
   - platform remove callback api final fixups (Uwe took many releases to
     get here, finally!)
   - Rust bindings for basic firmware apis and initial driver-core
     interactions.  It's not all that useful for a "write a whole driver
     in rust" type of thing, but the firmware bindings do help out the
     phy rust drivers, and the driver core bindings give a solid base on
     which others can start their work.  There is still a long way to go
     here before we have a multitude of rust drivers being added, but
     it's a great first step.
   - driver core const api changes.  This reached across all bus types,
     and there are some fix-ups for some not-common bus types that
     linux-next and 0-day testing shook out.  This work is being done to
     help make the rust bindings more safe, as well as the C code, moving
     toward the end-goal of allowing us to put driver structures into
     read-only memory.  We aren't there yet, but are getting closer.
   - minor devres cleanups and fixes found by code inspection
   - arch_topology minor changes
   - other minor driver core cleanups
 
 All of these have been in linux-next for a very long time with no
 reported problems.

The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
 samsung, imx, zynq and amlogic platoforms are farily small maintenance
 changes, either addressing minor mistakes or enabling additional hardware.
 
 The qualcomm platform changes add a number of features and are larger
 than the other ones combined, introducing the use of linux/cleanup.h
 across several drivers, adding support for Snapdragon X1E and other
 SoCs in platform drivers, a new "protection domain mapper" driver, and a
 "shared memory bridge" driver.
 
 The cznic "turris omnia" router based on Marvell Armada gets a platform
 driver that talks to the board specific microcontroller.
 
 The reset and cache subsystems get a few minor updates to SoC specific
 drivers, while the ff-a, scmi and optee firmware drivers get some
 code refactoring and new features.

619b92b9c8 I'm actually surprised this time. There aren't any new Qualcomm SoC clk
drivers. And there's zero diff in the core clk framework. Instead we have new
 clk drivers for STM and Sophgo, with Samsung^WGoogle in third for the diffstat
 because they introduced HSI0 and HSI2 clk drivers for Google's GS101 SoC (high
 speed interface things like PCIe, UFS, and MMC). Beyond those big diffs there's
 the usual updates to various clk drivers for incorrect parent descriptions or
 mising MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
 interesting here.
 
 New Drivers:
  - STM32MP257 SoC clk driver
  - Airoha EN7581 SoC clk driver
  - Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
  - Loongson-2k0500 and Loongson-2k2000 SoC clk driver
  - Add HSI0 and HSI2 clock controllers for Google GS101
  - Add i.MX95 BLK CTL clock driver
 
 Updates:
  - Allocate clk_ops dynamically for SCMI clk driver
  - Add support in qcom RCG and RCG2 for multiple configurations for the same frequency
  - Use above support for IPQ8074 NSS port 5 and 6 clocks to resolve issues
  - Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some boards
  - Cleanups and fixes for Qualcomm Stromer PLLs

Pull clk updates from Stephen Boyd:
 "I'm actually surprised this time. There aren't any new Qualcomm SoC
  clk drivers. And there's zero diff in the core clk framework.

  Instead we have new clk drivers for STM and Sophgo, with
  Samsung^WGoogle in third for the diffstat because they introduced HSI0
  and HSI2 clk drivers for Google's GS101 SoC (high speed interface
  things like PCIe, UFS, and MMC).

  Beyond those big diffs there's the usual updates to various clk
  drivers for incorrect parent descriptions or mising
  MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
  interesting here.

  New Drivers:
   - STM32MP257 SoC clk driver
   - Airoha EN7581 SoC clk driver
   - Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
   - Loongson-2k0500 and Loongson-2k2000 SoC clk driver
   - Add HSI0 and HSI2 clock controllers for Google GS101
   - Add i.MX95 BLK CTL clock driver

  Updates:
   - Allocate clk_ops dynamically for SCMI clk driver
   - Add support in qcom RCG and RCG2 for multiple configurations for
     the same frequency
   - Use above support for IPQ8074 NSS port 5 and 6 clocks to resolve
     issues
   - Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some
     boards

Stephen and Philipp, while reviewing patches, said that all of the aux
device creation and the register read/write code could be moved to the
reset subsystem, leaving the clock driver with no implementations of
reset_* functions at all. Move them.

6d89df6165 reset: ti-sci: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

c721f189e8 reset: Instantiate reset GPIO controller for shared reset-gpios
Devices sharing a reset GPIO could use the reset framework for
coordinated handling of that shared GPIO line.  We have several cases of
such needs, at least for Devicetree-based platforms.

If Devicetree-based device requests a reset line, while "resets"
Devicetree property is missing but there is a "reset-gpios" one,
instantiate a new "reset-gpio" platform device which will handle such
reset line.  This allows seamless handling of such shared reset-gpios
without need of changing Devicetree binding [1].

To avoid creating multiple "reset-gpio" platform devices, store the
Devicetree "reset-gpios" GPIO specifiers used for new devices on a
linked list.  Later such Devicetree GPIO specifier (phandle to GPIO
controller, GPIO number and GPIO flags) is used to check if reset
controller for given GPIO was already registered.

If two devices have conflicting "reset-gpios" property, e.g. with
different ACTIVE_xxx flags, this would allow to spawn two separate
"reset-gpio" devices, where the second would fail probing on busy GPIO
request.

    across multiple subsystems
 
  - Qualcomm Snapdragon gains support for SM8650 and X1E along with
    added features for some other SoCs
 
  - Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195,
    and driver support for MT8188 along with some code refactoring.
 
  - Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream

4a6756f56b reset: Fix crash when freeing non-existent optional resets
When obtaining one or more optional resets, non-existent resets are
stored as NULL pointers, and all related error and cleanup paths need to
take this into account.

Currently only reset_control_put() and reset_control_bulk_put()
get this right.  All of __reset_control_bulk_get(),
of_reset_control_array_get(), and reset_control_array_put() lack the
proper checking, causing NULL pointer dereferences on failure or
release.

Fix this by moving the existing check from reset_control_bulk_put() to
__reset_control_put_internal(), so it applies to all callers.
The double check in reset_control_put() doesn't hurt.

fed2ef7aba reset: Annotate struct reset_control_array with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct reset_control_array.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

f8fd5c2483 This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone
 was on vacation (yours truly included). We did lose a couple clk drivers this
 time around because nobody was using those devices. That skews the diffstat a
 bit, but either way, nothing looks out of the ordinary here. The usual suspects
 are chugging along adding support for more SoCs and fixing bugs.
 
 If I had to choose, I'd say the theme for the past few months has been
 "polish". There's quite a few patches that migrate to
 devm_platform_ioremap_resource() in here. And there's more than a handful of
 patches that move the NR_CLKS define from the DT binding header to the driver.
 There's even patches that migrate drivers to use clk_parent_data and clk_hw to
 describe clk tree topology. It seems that the spring (summer?) cleaning bug got
 some folks, or the semiconductor shortage finally hit the software side.
 
 New Drivers:
  - StarFive JH7110 SoC clock drivers
  - Qualcomm IPQ5018 Global Clock Controller driver
  - Versa3 clk generator to support 48KHz playback/record with audio codec on
    RZ/G2L SMARC EVK
 
 Removed Drivers:
  - Remove non-OF mmp clk drivers
  - Remove OXNAS clk driver
 
 Updates:
  - Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc
  - Move defines for numbers of clks (NR_CLKS) from DT headers to drivers
  - Introduce kstrdup_and_replace() and use it
  - Add PLL rates for Rockchip rk3568
  - Add the display clock tree for Rockchip rv1126
  - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs
  - Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource()
  - Fix function name in a comment in ccu_mmc_timing.c
  - Parameter name correction for ccu_nkm_round_rate()
  - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative
    parent rates when determining clock rates
  - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
  - Support finding closest (as opposed to closest but not higher) clock rate
    for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0
  - Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks
  - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to
    the interconnect drivers
  - Fix various PM runtime bugs across many Qualcomm clk drivers
  - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
  - Add network related resets on Qualcomm IPQ4019
  - Add a couple missing USB related clocks to Qualcomm IPQ9574
  - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller
  - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are
    added, while PCIe pipe clock, SDCC rcg ops are corrected
  - Add missing GDSCs to and correct GDSCs for the SC8280XP global clock controller driver
  - Support retention for the Qualcomm SC8280XP display clock controller GDSCs.
  - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE to fix
    issues with missing parent clocks across sc7180, sm7150, sm6350 and sm8250,
    while sm8450 is corrected to use floor ops
  - Correct Qualcomm SM6350 GPU clock controller's clock supplies
  - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver
  - Add missing OXILICX GDSC to Qualcomm MSM8226 GCC
  - Change the delay in the Qualcomm reset controller to fsleep() for correctness
  - Extend the Qualcomm SM83550 Video clock controller to support SC8280XP
  - Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and R-Car H3,
    M3-W, and M3-N SoCs
  - Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M
  - Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five
  - Add the PDM IPC clock for i.MX93
  - Add 519.75MHz frequency support for i.MX9 PLL
  - Simplify the .determine_rate() implementation for i.MX GPR mux
  - Make the i.MX8QXP LPCG clock use devm_platform_ioremap_resource()
  - Add the audio mux clock to i.MX8
  - Fix the SPLL2 MULT range for PLLv4
  - Update the SPLL2 type in i.MX8ULP
  - Fix the SAI4 clock on i.MX8MP

  - Drop restrictions for i.MX PLL14xx and fix its max prediv value
  - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to allow
    glitch free switching

bad8a8afe1 reset: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The Nuvoton MA35D1 reset controller is only present on Nuvoton MA35
SoCs.  Hence add a dependency on ARCH_MA35, to prevent asking the user
about this driver when configuring a kernel without MA35 SoC support.
Also, do not enable the driver by default when merely compile-testing.

While at it, fix a misspelling of "Nuvoton".

e81507acdc Nothing looks out of the ordinary in this batch of clk driver updates. There
are a couple patches to the core clk framework, but they're all basically
 cleanups or debugging aids. The driver updates and new additions are dominated
 in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
 new drivers for various SoCs, and MediaTek gained a bunch of drivers for
 MT8188. The MediaTek drivers are being modernized as well, so there are
 updates all over that vendor's clk drivers. There's also a couple other new clk
 drivers in here, for example the Starfive JH7110 SoC support is added.
 
 Outside of the two major SoC vendors though, we have the usual collection of
 non-critical fixes and cleanups to various clk drivers. It's good to see that
 we're getting more cleanups and modernization patches. Maybe one day we'll be
 able to properly split clk providers from clk consumers.
 
 Core:
  - Print an informational message before disabling unused clks
 
 New Drivers:
  - BCM63268 timer clock and reset controller
  - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
    MT8195 SoCs
  - Mediatek MT8188 SoC clk drivers
  - Clock driver for Sunplus SP7021 SoC
  - Clk driver support for Loongson-2 SoCs
  - Clock driver for Skyworks Si521xx I2C PCIe clock generators
  - Initial Starfive JH7110 clk/reset support
  - Global clock controller drivers for Qualcomm SM7150, IPQ9574, MSM8917 and IPQ5332 SoCs
  - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P SoCs
 
 Updates:
  - Shrink size of clk_fractional_divider a little
  - Convert various clk drivers to devm_of_clk_add_hw_provider()
  - Convert platform clk drivers to remove_new()
  - Converted most Mediatek clock drivers to struct platform_driver
  - MediaTek clock drivers can be built as modules
  - Reimplement Loongson-1 clk driver with DT support
  - Migrate socfpga clk driver to of_clk_add_hw_provider()
  - Support for i3c clks on Aspeed ast2600 SoCs
  - Add clock generic devm_clk_hw_register_gate_parent_data
  - Add audiomix block control for i.MX8MP
  - Add support for determine_rate to i.MX composite-8m
  - Let the LCDIF Pixel clock of i.MX8MM and i.MX8MN set parent rate
  - Provide clock name in error message for clk-gpr-mux on get parent failure
  - Drop duplicate imx_clk_mux_flags macro
  - Register the i.MX8MP Media Disp2 Pix clock as bus clock
  - Add Media LDB root clock to i.MX8MP
  - Make i.MX8MP nand_usdhc_bus clock as non-critical
  - Fix the rate table for i.MX fracn-gppll
  - Disable HW control for the fracn-gppll in order to be controlled by
    register write
  - Add support for interger PLL in fracn-gppll
  - Add mcore_booted module parameter to i.MX93 provider
  - Add NIC, A55 and ARM PLL clocks to i.MX93
  - Fix i.MX8ULP XBAR_DIVBUS and AD_SLOW clock parents
  - Use "divider closest" clock type for PLL4_PFD dividers on i.MX8ULP to
    get more accurate clock rates
  - Mark the MU0_Bi and TPM5 clocks on i.MX8ULP as critical
  - Update some of the i.MX critical clocks flags to allow glitchless
    on-the-fly rate change.
  - Add I2C5 clock on Renesas R-Car V3H
  - Exynos850: Add CMU_G3D clock controller for the Mali GPU
  - Extract Exynos5433 (ARM64) clock controller power management code to
    common driver parts
  - Exynos850: make PMU_ALIVE_PCLK clock critical
  - Add Audio, thermal, camera (CSI-2), Image Signal Processor/Channel
    Selector (ISPCS), and video capture (VIN) clocks on Renesas R-Car V4H
  - Add video capture (VIN) clocks on Renesas R-Car V3H
  - Add Cortex-A53 System CPU (Z2) clocks on Renesas R-Car V3M and V3H
  - Support for Stromer Plus PLL on Qualcomm IPQ5332
  - Add a missing reset to Qualcomm QCM2290

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "Nothing looks out of the ordinary in this batch of clk driver updates.

  There are a couple patches to the core clk framework, but they're all
  basically cleanups or debugging aids. The driver updates and new
  additions are dominated in the diffstat by Qualcomm and MediaTek
  drivers. Qualcomm gained a handful of new drivers for various SoCs,
  and MediaTek gained a bunch of drivers for MT8188. The MediaTek
  drivers are being modernized as well, so there are updates all over
  that vendor's clk drivers. There's also a couple other new clk drivers
  in here, for example the Starfive JH7110 SoC support is added.

  Outside of the two major SoC vendors though, we have the usual
  collection of non-critical fixes and cleanups to various clk drivers.
  It's good to see that we're getting more cleanups and modernization
  patches. Maybe one day we'll be able to properly split clk providers
  from clk consumers.

  Core:
   - Print an informational message before disabling unused clks

  New Drivers:
   - BCM63268 timer clock and reset controller
   - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
     MT8195 SoCs

     MSM8917 and IPQ5332 SoCs
   - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P
     SoCs

d1aae06630 clk: starfive: Avoid casting iomem pointers
Let's use a wrapper struct for the auxiliary_device made in
jh7110_reset_controller_register() so that we can stop casting iomem
pointers. The casts trip up tools like sparse, and make for some awkward
casts that are largely unnecessary. While we're here, change the
allocation from devm and actually free the auxiliary_device memory in
the release function. This avoids any use after free problems where the
parent device driver is unbound from the device but the
auxiliuary_device is still in use accessing devm freed memory.

Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as

b6d7406cd7 reset: starfive: jh71x0: Use 32bit I/O on 32bit registers
We currently use 64bit I/O on the 32bit registers. This works because
there are an even number of assert and status registers, so they're only
ever accessed in pairs on 64bit boundaries.

There are however other reset controllers for audio and video on the
JH7100 SoC with only one status register that isn't 64bit aligned so
64bit I/O results in an unaligned access exception.

Switch to 32bit I/O in preparation for supporting these resets too.

The StarFive JH7100 SoC has additional reset controllers for audio and

Linus Torvalds
bdc753c7fc Here's the main clk pull request for this merge window. We have some
late breaking reports that a patch series to rework clk rate range
 support broke boot on some devices, so I've left that branch out of this
 PR. Hopefully we can get to that next week, or punt on it and let it
 bake another cycle. That means we don't really have any changes to the
 core framework this time around besides a few typo fixes. Instead this
 is all clk driver updates and fixes.
 
 The usual suspects are here (again), with Qualcomm dominating the
 diffstat. We look to have gained support for quite a few new Qualcomm
 SoCs and Dmitry worked on updating many of the existing Qualcomm drivers
 to use clk_parent_data. After that we have MediaTek drivers getting some
 much needed updates, in particular to support GPU DVFS. There are also
 quite a few Samsung clk driver patches, but that's mostly because there
 was a maintainer change and so last release we missed some of those
 patches.
 
 Overall things look normal, but I'm slowly reviewing core framework code
 nowadays and that shows given the rate range patches had to be yanked
 last minute. Let's hope this situation changes soon.
 
 New Drivers:
  - Support for Renesas VersaClock7 clock generator family

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "We have some late breaking reports that a patch series to rework clk
  rate range support broke boot on some devices, so I've left that
  branch out of this. Hopefully we can get to that next week, or punt on
  it and let it bake another cycle. That means we don't really have any
  changes to the core framework this time around besides a few typo
  fixes. Instead this is all clk driver updates and fixes.

  The usual suspects are here (again), with Qualcomm dominating the
  diffstat. We look to have gained support for quite a few new Qualcomm
  SoCs and Dmitry worked on updating many of the existing Qualcomm
  drivers to use clk_parent_data. After that we have MediaTek drivers
  getting some much needed updates, in particular to support GPU DVFS.
  There are also quite a few Samsung clk driver patches, but that's
  mostly because there was a maintainer change and so last release we
  missed some of those patches.

  Overall things look normal, but I'm slowly reviewing core framework
  code nowadays and that shows given the rate range patches had to be
  yanked last minute. Let's hope this situation changes soon.

  New Drivers:
   - Support for Renesas VersaClock7 clock generator family
   - Add Spreadtrum UMS512 SoC clk support
   - New clock drivers for MediaTek Helio X10 MT6795
   - Display clks for Qualcomm SM6115, SM8450

ff6862c23d ARM: driver updates for 6.1
The drivers branch for 6.1 is a bit larger than for most releases.  Most
 of the changes come from SoC maintainers for the drivers/soc subsystem:
 
  - A new driver for error handling on the NVIDIA Tegra
    'control backbone' bus.
 
  - A new driver for Qualcomm LLCC/DDR bandwidth measurement
 
  - New Rockchip rv1126 and rk3588 power domain drivers
 
  - DT binding updates for memory controllers, older Rockchip
    SoCs, various Mediatek devices, Qualcomm SCM firmware
 
  - Minor updates to Hisilicon LPC bus, the Allwinner SRAM
    driver, the Apple rtkit firmware driver, Tegra firmware
 
  - Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
    Tegra, Qualcomm, Broadcom, NXP, ...)
 
 There are also some separate subsystem with downstream maintainers that
 merge updates this way:
 
  - Various updates and new drivers in the memory controller
    subsystem for Mediatek and Broadcom SoCs
 
  - Small set of changes in preparation to add support for FF-A
    v1.1 specification later, in the Arm FF-A firmware subsystem
 
  - debugfs support in the PSCI firmware subsystem

Add support for the resets on Microchip's PolarFire SoC (MPFS).
Reset control is a single register, wedged in between registers for
clock control. To fit with existed DT etc, the reset controller is
created using the aux device framework & set up in the clock driver.

51fd191422 reset: microchip-sparx5: issue a reset on startup
Originally this was used in by the switch core driver to issue a reset.
But it turns out, this isn't just a switch core reset but instead it
will reset almost the complete SoC.

Instead of adding almost all devices of the SoC a shared reset line,
issue the reset once early on startup. Keep the reset controller for
backwards compatibility, but make the actual reset a noop.

8a4e6154fb reset: tps380x: Add TPS380x device driver supprt
The TI TPS380x family [1] is a voltage supervisor with a dedicated
manual reset (mr) line input and a reset output. The chip(s) have a
build in reset delay, depending on the chip partnumber. This simple
driver addresses this so the cosumer don't need to care about it.

c4ada3ca99 reset: reset-simple should depends on HAS_IOMEM
The reset-simple driver does not build on all architecuters as it requires
devm_ioremap_resource() which is only built when CONFIG_HAS_IOMEM is enabled
in the kenrel. Fix the following error by depending on CONFIG_HAS_IOMEM:

drivers/reset/reset-simple.o: in function `reset_simple_probe':
 reset-simple.c:(.text+0x3aa): undefined reference to `devm_ioremap_resource'

Fixes: 18d1909be3 ("reset: allow building of reset simple driver if expert config selected")

2d0f3f13a9 Merge branch 'nuvoton/newsoc' into arm/newsoc
Merge the new SoC support from Tomer Maimon:
 "This patchset  adds initial support for the Nuvoton
  Arbel NPCM8XX Board Management controller (BMC) SoC family.

  The Nuvoton Arbel NPCM8XX SoC is a fourth-generation BMC.
  The NPCM8XX computing subsystem comprises a quadcore ARM
  Cortex A35 ARM-V8 architecture.

  This patchset adds minimal architecture and drivers such as:
  Clocksource, Clock, Reset, and WD.

  Some of the Arbel NPCM8XX peripherals are based on Poleg NPCM7XX.

  This patchset was tested on the Arbel NPCM8XX evaluation board."

I'm leaving out the clk controller driver, which is still under
review.
