Add support for the power areas in the Renesas R-Car M3-W+ (R8A77961)
SoC to the R-Car System Controller driver.
R-Car M3-W+ (aka R-Car M3-W ES3.0) is very similar to R-Car
M3-W (R8A77960), which allows for both SoCs to share a driver:
- R-Car M3-W+ lacks the A2VC power area, so its area must be
nullified,
- The existing support for the SYSCEXTMASK register added in commit
9bd645af9d2a49ac ("soc: renesas: r8a7796-sysc: Fix power request
conflicts") applies to ES3.0 and later only.
As R-Car M3-W+ uses a different compatible value, differentiate
based on that, instead of on the ES version.
Based on a patch in the BSP by Dien Pham <dien.pham.ry@renesas.com>.

the Product ID Number with R-Car M3-W (R8A77960), but differs in CUT

Add CONFIG_ARCH_R8A77960 as a new config symbol for R-Car M3-W
(R8A77960), to replace CONFIG_ARCH_R8A7796, and avoid confusion with
R-Car M3-W+ (R8A77961), which will use CONFIG_ARCH_R8A77961.
Note that for now, CONFIG_ARCH_R8A7796 is retained, and just selects
CONFIG_ARCH_R8A77960. This relaxes dependencies of other subsystems on
the SoC configuration symbol, and provides a smooth transition path for
config files through "make oldconfig".

If the DTB for a device with an RZ/A2 SoC lacks a device node for the
BSID register, the ID validation code falls back to using a register at
address 0x0, which leads to undefined behavior (e.g. reading back a
random value).
This could be fixed by letting fam_rza2.reg point to the actual BSID
register. However, the hardcoded fallbacks were meant for backwards
compatibility with old DTBs only, not for new SoCs. Hence fix this by
validating renesas_family.reg before using it.

Recent R-Car Gen3 SoCs added an External Request Mask Register to the
System Controller (SYSC). This register allows to mask external power
requests for CPU or 3DG domains, to prevent conflicts between powering
off CPU cores or the 3D Graphics Engine, and changing the state of
another power domain through SYSC, which could lead to CPG state machine
lock-ups.
Add support for making use of this register. Take into account that the
register is optional, and that its location and contents are
SoC-specific.
Note that the issue fixed by this cannot happen in the upstream kernel,
as upstream has no support for graphics acceleration yet. SoCs lacking
the External Request Mask Register may need a different mitigation in
the future.

firmware driver.
- The Samsung Exynos family gains a new Chipid driver exporting using
the soc device sysfs interface
- A similar socinfo driver for Qualcomm Snapdragon chips.
- A firmware driver for the NXP i.MX DSP IPC protocol using shared
memory and a mailbox
Other changes:
- The i.MX reset controller driver now supports the NXP i.MX8MM chip
- Amlogic SoC specific drivers gain support for the S905X3 and A311D
chips
- A rework of the TI Davinci framebuffer driver to allow important
cleanups in the platform code
- A couple of device drivers for removed ARM SoC platforms are
removed. Most of the removals were picked up by other maintainers,
this contains whatever was left"

Pull ARM SoC platform updates from Arnd Bergmann:
"The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.
The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody
is using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still
in active use and are converted to the ARCH_MULTIPLATFORM build,
meaning that we can compile a kernel that works on these along with
most other ARMv5 platforms. Changes toward that goal are also merged
for IOP32x, but additional work is needed to complete this. Patches
for the remaining ARMv5 platforms have started but need more work and
some testing.
Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.
Other changes include a cleanup of the ST-Ericsson ux500 platform and
the move of the TI Davinci platform to a new clocksource driver"
[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new
warnings that I most definitely do not want to see during the merge
window as that could hide other issues.
So the COMPILE_TEST option got disabled for them again - Linus ]

TISCI protocol supports for enabling the device either with exclusive
permissions for the requesting host or with sharing across the hosts.
There are certain devices which are exclusive to Linux context and
there are certain devices that are shared across different host contexts.
So add support for getting this information from DT by increasing
the power-domain cells to 2.
For keeping the DT backward compatibility intact, defaulting the
device permissions to set the exclusive flag set. In this case the
power-domain-cells is 1.

Samsung soc drivers changes for v5.4
Add Exynos Chipid driver for identification of product IDs and SoC
revisions. The driver also exposes chipid regmap, later to be used by
Exynos Adaptive Supply Voltage driver (adjusting voltages to different
revisions of same SoC).

The move of the IXP4xx SoC drivers exposed their config options on all
platforms.
Fix this by wrapping them inside an ARCH_IXP4XX or COMPILE_TEST block.

Currently the R-Mobile "always-on" PM Domain is implemented by returning
-EBUSY from the generic_pm_domain.power_off() callback, and doing
nothing in the generic_pm_domain.power_on() callback. However, this
means the PM Domain core code is not aware of the semantics of this
special domain, leading to boot warnings like the following on
SH/R-Mobile SoCs:
sh_cmt e6130000.timer: PM domain c5 will not be powered off
Fix this by making the always-on nature of the domain explicit instead,
by setting the GENPD_FLAG_ALWAYS_ON flag. This removes the need for the
domain to provide power control callbacks.

In commit 40d8aff614f7 ("soc: samsung: chipid: Convert exynos-chipid
driver to use the regmap API") of_find_compatible_node() call was
substituted with syscon_regmap_lookup_by_compatible() but also an error
log was added for case where lookup fails. On multiplatform the lookup
will always fail on any non-samsung device so the log is incorrect.
Remove the error log and just return an error code from
syscon_regmap_lookup_by_compatible() which internally calls
of_find_compatible_node().

The variable np in function meson_gx_socinfo_init takes the return value
of of_find_compatible_node, which gets a node but does not put it. If
this node is not put it may cause a memory leak. Hence put np after its
usefulness has been exhausted.

is a memory leak of soc_dev_attr->revision and soc_dev_attr
