0c56f949f6 soc: renesas: Add PWC support for RZ/V2M
The Renesas RZ/V2M External Power Sequence Controller (PWC)
IP is capable of:
* external power supply on/off sequence generation
* on/off signal generation for the LPDDR4 core power supply (LPVDD)
* key input signals processing
* general-purpose output pins

Add the corresponding device driver.

GPIOLIB and PINCTRL config options are required by all ARM32/ARM64/RISC-V

architecture just explicitly select them under SOC_RENESAS config option
which will be visible for all the three architectures (if ARCH_RENESAS is
enabled).

088659ad2a soc: renesas: Kconfig: Introduce ARCH_RZG2L config option
The Renesas RZ/G2L, RZ/G2LC, RZ/G2UL and RZ/V2L SoCs have identical IP
blocks for which drivers are common.  To avoid updating the Kconfig
files for drivers in common to each SoC, introduce the ARCH_RZG2L config
option.
The ARCH_RZG2L config option will be selected by the above mentioned
SoCs, and the ARCH_RZG2L config option will be used as a dependency for
the drivers in common.

While at it, move PM and PM_GENERIC_DOMAINS under the ARCH_RZG2L config
option instead of keeping it for individual SoCs.

408324a3c5 ARM: shmobile: Enable ARM_GLOBAL_TIMER on Cortex-A9 MPCore SoCs
SH-Mobile AG5 and R-Car H1 SoCs are based on the Cortex-A9 MPCore, which
includes a global timer.

Enable the ARM global timer on these SoCs, which will be used for:
  - the scheduler clock, improving scheduler accuracy from 10 ms to 3 or
    4 ns,
  - delay loops, allowing removal of calls to shmobile_init_delay() from
    the corresponding machine vectors.

Note that when using an old DTB lacking the global timer, the kernel
will still work.  However, loops-per-jiffies will no longer be preset,
and the delay loop will need to be calibrated during boot.

b925adfceb soc: renesas: Add ARCH_R8A7795[01] for existing R-Car H3
Despite using the same compatible values ("r8a7795"-based) because of
historical reasons, R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+
(R8A77951) are really different SoCs, with different part numbers.

Reflect this in the SoC configuration, by adding CONFIG_ARCH_R8A77950
and CONFIG_ARCH_R8A77951 as new config symbols.  These are intended to
replace CONFIG_ARCH_R8A7795, and will allow making support for early SoC
revisions optional.

Note that for now, CONFIG_ARCH_R8A7795 is retained, and just selects
CONFIG_ARCH_R8A77950 and CONFIG_ARCH_R8A77951.  This relaxes
dependencies of other subsystems on the SoC configuration symbol, and
provides a smooth transition path for config files through "make
oldconfig".

bdde3d3ec9 soc: renesas: rcar-sysc: Add R8A77961 support
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>.

arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for

Increase consistency with other vendors by moving the SoC-specific

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.
