bdbddf72a2 soc: driver updates for 7.0
There are are a number of to firmware drivers, in particular the TEE
 subsystem:
 
   - a bus callback for TEE firmware that device drivers can register to
   - sysfs support for tee firmware information
   - minor updates to platform specific TEE drivers for AMD, NXP, Qualcomm
     and the generic optee driver
   - ARM SCMI firmware refactoring to improve the protocol discover
     among other fixes and cleanups
   - ARM FF-A firmware interoperability improvements
 
 The reset controller and memory controller subsystems gain support for
 additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
 SpacemiT.
 
 Most of the other changes are for random drivers/soc code. Among
 a number of cleanups and newly added hardware support, including:
 
  - Mediatek MT8196 DVFS power management and mailbox support
 
  - Qualcomm SCM firmware and MDT loader refactoring, as part of
    the new Glymur platform support.
 
  - NXP i.MX9 System Manager firmware support for accessing the
    syslog
 
  - Minor updates for TI, Renesas, Samsung, Apple, Marvell and AMD
    SoCs.

  - Arm FF-A firmware support gains support for v1.1 specification features,

  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.

Randy reported a randconfig build issue against linux-next:

    WARNING: unmet direct dependencies detected for ERRATA_ANDES
      Depends on [n]: RISCV_ALTERNATIVE [=n] && RISCV_SBI [=y]
      Selected by [y]:
      - ARCH_R9A07G043 [=y] && SOC_RENESAS [=y] && RISCV [=y] && NONPORTABLE [=y] && RISCV_SBI [=y]

       59 | void __init_or_module andes_errata_patch_func(struct alt_entry *begin, struct alt_entry *end,

On RISC-V, alternatives are not usable in XIP kernels, which this
randconfig happened to select.  Rather than add a check for whether
alternatives are available before selecting the ERRATA_ANDES config
option, rework the R9A07G043 Kconfig entry to depend on the
configuration options required to support its non-standard cache
coherency implementation.

Without these options enabled, the SoC is effectively non-functional to
begin with, so there's an extra benefit in preventing the creation of
non-functional kernels.

The "if RISCV_DMA_NONCOHERENT" can be dropped, as ERRATA_ANDES_CMO will
select it.

c1ec4b450a soc: renesas: Make ARCH_R9A07G043 (riscv version) depend on NONPORTABLE
Drew found "CONFIG_DMA_GLOBAL_POOL=y causes ADMA buffer alloc to fail"
the log looks like:

    mmc0: Unable to allocate ADMA buffers - falling back to standard DMA

The logic is: generic riscv defconfig selects ARCH_RENESAS then
ARCH_R9A07G043 which selects DMA_GLOBAL_POOL, which assumes all
non-dma-coherent riscv platforms have a dma global pool, this assumption
seems not correct. And I believe DMA_GLOBAL_POOL should not be
selected by ARCH_SOCFAMILIY, instead, only ARCH under some specific
conditions can select it globaly, for example NOMMU ARM and so on,
because it's designed for special cases such as "nommu cases where
non-cacheable memory lives in a fixed place in the physical address
map" as pointed out by Robin.

Fix the issue by making ARCH_R9A07G043 (riscv version) depend on
NONPORTABLE, thus generic defconfig won't select ARCH_R9A07G043 by
default. And even for random config case, there will be less debug
effort once we see NONPORTABLE is enabled.

18ecaaea21 soc: renesas: Remove r8a77950 arch
R-Car H3 ES1.* was only available to an internal development group and
needed a lot of quirks and workarounds.  These become a maintenance
burden now, so our development group decided to remove upstream support
and disable booting for this SoC.  Public users only have ES2 onwards.

Remove the architecture which describes H3 ES1.*.

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
Renesas SoCs, so instead of selecting them under ARCH_RENESAS for each
architecture just explicitly select them under SOC_RENESAS config option
which will be visible for all the three architectures (if ARCH_RENESAS is
enabled).

Without these configs, the clocks used by the PCI bridge are not

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.
