Power area A2VC0 was removed in revision ES2.0, cfr. R-Car Gen3 Hardware
User's Manual rev. 0.53E.

Hence remove it from the power area table when not running on ES1.x.

This is in line with the goal to:
  1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
     for now,
  2. Make it clear which code supports ES1.x, so it can easily be
     identified and removed later, when production SoCs are deemed
     ubiquitous.

afa6f53df6 soc: renesas: rcar-sysc: Add support for fixing up power area tables
The same SoC may have different power areas, depending on SoC revision.
One option is to use different sets of power area tables for each SoC
revision.  However, if the differences are small, it is much more
space-efficient to have a single set of tables, and fix those up at
runtime instead.

Hence provide a helper to NULLify power areas that do not exist on some
revisions (NULLified power areas are skipped during the registration
phase), and support for an optional initialization callback to e.g. fix
up power area tables.

an early_initcall().  However, this means the driver cannot check the

On i.MX6QP, due to hardware erratum ERR009619, the PRE clocks may be
stalled during the power up sequencing of the PU power domain. As this
may lead to a complete loss of display output, the recommended
workaround is to keep the PU domain enabled during normal system
operation.

Implement this by rejecting the domain power down request on the
affected SoC.

52835d59fc soc: ti: Add ti_sci_pm_domains driver
Introduce a ti_sci_pm_domains driver to act as a generic pm domain
provider to allow each device to attach and associate it's ti-sci-id so
that it can be controlled through the TI SCI protocol.

This driver implements a simple genpd where each device node has a
phandle to the power domain node and also must provide an index which
represents the ID to be passed with TI SCI representing the device using
a single phandle cell. The driver manually parses the phandle to get the
cell value. Through this interface the genpd dev_ops start and stop
hooks will use TI SCI to turn on and off each device as determined by
pm_runtime usage.

Tegra132 and Tegra210 support the flowctrl module and so add initial
support for these devices.

Please note that Tegra186 does not support the flowctrl module, so
update the initialisation function such that we do not fall back and
attempt to map the 'hardcoded' address range for Tegra186. Furthermore
64-bit Tegra devices have always had the flowctrl node defined in their
device-tree and so only use the 'hardcoded' addresses for 32-bit Tegra
devices.

The flowctrl driver is required for both ARM and ARM64 Tegra devices
and in order to enable support for it for ARM64, move the Tegra flowctrl
driver into drivers/soc/tegra.

By moving the flowctrl driver, tegra_flowctrl_init() is now called by
via an early initcall and to prevent this function from attempting to
mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()'
is also added.

The Makefiles currently controlling compilation of this code is:

drivers/soc/tegra/Makefile:obj-y += fuse/
drivers/soc/tegra/fuse/Makefile:obj-y += fuse-tegra.o

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

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

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

5052de8def soc: qcom: smd: Transition client drivers from smd to rpmsg
By moving these client drivers to use RPMSG instead of the direct SMD
API we can reuse them ontop of the newly added GLINK wire-protocol
support found in the 820 and 835 Qualcomm platforms.

As the new (RPMSG-based) and old SMD implementations are mutually
exclusive we have to change all client drivers in one commit, to make
sure we have a working system before and after this transition.

3a317f5235 soc: imx: gpc: fix the wrong using of regmap cache
Without providing the proper reg_defaults, the regmap registers first
read out may be always 0 if enabling cache, which results in the
following issue we met.
e.g. During driver probe in imx6_pm_domain_power_on():
regmap_read(pd->regmap, pd->reg_offs + GPC_PGC_PUPSCR_OFFS, &val);
The PGC_PUPSCR register val is always 0 but it's actually 0xf01 in HW.

Since GPC registers are tightly related to CPU bring up and may be
changed in bootloader, we don't want to provide defaults.
And the cache really does not save too much for GPC module.

Therefore, simply disable cache to fix the issue and make life easy.

a0ebf66267 soc: samsung: Do not build ARMv7 PMU drivers on ARMv8
The Exynos Power Management Unit (PMU) drivers contain quite large
static arrays of register values necessary for given Exynos SoC to enter
low power mode.  All this data is useless for ARMv8 SoC like
Exynos5433, because the image will not be shared between ARMv7 and
ARMv8.

Add additional Kconfig symbol for selecting the SoC-specific driver
addons thus skipping the useless data in the final image (this is
similar approach to chosen for Exynos clock controller drivers):
 - exynos-pmu driver will be compiled on both architectures ARMv7
   and ARMv8,
 - additional driver_data for ARMv7 SoCs will not be built on ARMv8
   and a macro will return NULL for them in of_device_id - this should
   be safe as these compatibles cannot match on ARMv7 and driver
   anyway handles NULL driver_data,
 - on ARMv8 compile only exynos-pmu driver which exposes the
   syscon-regmap for PMU address space.

721cabf6c6 soc: imx: move PGC handling to a new GPC driver
This is an almost complete re-write of the previous GPC power gating control
code found in the IMX architecture code. It supports both the old and the new
DT binding, allowing more domains to be added later and generally makes the
driver easier to extend, while keeping compatibility with existing DTBs.

As the result, all functionality regarding the power gating controller
gets removed from the IMX architecture GPC driver.  It keeps only the
IRQ controller code in the architecture, as this is closely coupled to
the CPU idle implementation.

b2e3c4319d ARM: SoC driver updates
Driver updates for ARM SoCs.
 
 A handful of driver changes this time around. The larger changes are:
 
  - Reset drivers for hi3660 and zx2967
  - AHCI driver for Davinci, acked by Tejun and brought in here due to
    platform dependencies
  - Cleanups of atmel-ebi (External Bus Interface)
  - Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
    register range on the SoCs)
  - PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)

6ae52c65e0 ARM: SoC platform updates
In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
 C code changes for SoC platforms. This release cycle the diffstat is quite
 nice, in that we're removing 3x the amount of code that's being added.
 
 The main reason for this is that there's a removal of camera drivers for
 Freescale i.MX chips (driver was removed so the device registration isn't
 needed any more). There's also removal of display initialization code for OMAP
 that is no longer needed.
 
 The rest are mostly minor tweaks and cleanups; constification on Samsung
 platforms, cleanup of ux500 platform data, purge of other unused platform
 data/device seutp on i.MX and other good stuff.
 
 New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

a3919caaa2 remoteproc updates for v4.11
This introduces support for booting the dedicated sensor core in the
 Qualcomm MSM8996, updates the Qualcomm ADSP and Hexagon drivers to
 utilize SMD subdevice helpers for properly handle shutdowns and restarts
 of the remoteproc, add virtio support to the ST remoteproc and refactor
 the Qualcomm Hexagon driver to handle variations between platforms.
 
 The support code for parsing, loading and authenticating Qualcomm
 firmware files (MDT) is refactored and move to drivers/soc/qcom, to
 allow for non-remoteproc drivers to utilize this.
 
 Finally it brings some cleanups to the remoteproc core.

01625cc5e6 remoteproc: qcom: mdt_loader: Use signed type for offset
In the transition from using rproc_da_to_va(), the type of the load
offset became unsigned. This causes the subsequent check to let negative
values less than p_memsz + mem_size through and we write outside of the
buffer.

Change the type back to a signed value to catch this.

b13b2330aa soc: samsung: pm_domains: Read domain name from the new label property
Device tree nodes for each power domain should use generic "power-domain"
name, so using it as a domain name doesn't give much benefits. This patch
adds support for human readable names defined in 'label' property. Such
names are visible to userspace and makes debugging much easier. When no
'label' property is found, driver keeps using the name constructed from
full node name.

We don't currently have anything else for drivers/soc to

 moving PM code into drivers with the recently posted SRAM
 changes. Anyways, sent as a separate pull request to make
 it easy to group the ARM SoC pull requests.

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

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

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

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

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

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

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

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

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

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

b8d2798f32 This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)
  - i.MX imx6ull
  - Socionext's UniPhier SoC CPUs
  - Mediatek MT2701 SoCs
  - Rockchip rk1108 SoCs
  - Qualcomm MSM8994/MSM8992 SoCS

  - Oxford Semiconductor OX820 and OX810SE SoCs
  - Renesas RZ/G1M and RZ/GIE SoCs
  - Renesas R-Car RST driver for mode pin states
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver
  - Rockchip rk3399,rk3066 PLL optimizations
  - i.MX LVDS display glitch fixes and AV PLL precision improvements
  - Qualcomm MSM8996 GPU GDSCs, hw controlled GDSCs, and Alpha PLL support

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

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

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

With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported:

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

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

Other guts accesses, such as reading RCW, should eventually be moved

Identification is done using the Product Register or Common Chip Code

fallback if missing.

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

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

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

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

The newly introduced pm_genpd_remove reverts the initialization done
by pm_genpd_init and is necessary in the error path of the rockchip
power-domain driver.

Without it the driver will in the error case cleanup the devm-allocated

deactivation of unused domains (and probably later genpd accesses as
well) fail by accessing invalid pointers.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

There is no need to select PM_GENERIC_DOMAINS_OF if OF is set, so we can

8df127456f soc/tegra: pmc: Enable XUSB partitions on boot
The Tegra XHCI driver does not currently manage the Tegra XUSB power
partitions and so it these partitions have not been enabled by the
bootloader then the system will crash when probing the XHCI device.

While proper support for managing the power partitions is being
developed to the XHCI driver for Tegra, for now power on all the XUSB
partitions for USB host and super-speed on boot if the XHCI driver is
enabled.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

e465007a7a ARM: EXYNOS: Move pm_domains driver to drivers/soc/samsung
Exynos PM domains driver does not have mach-specific dependencies so it
can be safely moved out of arm/mach-exynos to drivers/soc. This in
future will allow re-using it on ARM64 boards.

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

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

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

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

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