soc: renesas: Rework Kconfig and Makefile logic The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.

soc: renesas: Identify SoC and register with the SoC bus Identify the SoC type and revision, and register this information with the SoC bus, so it is available under /sys/devices/soc0/, and can be checked where needed using soc_device_match(). Identification is done using the Product Register or Common Chip Code Register, as declared in DT (PRR only for now), or using a hardcoded fallback if missing. Example: Detected Renesas R-Car Gen2 r8a7791 ES1.0 ... # cat /sys/devices/soc0/{machine,family,soc_id,revision} Koelsch R-Car Gen2 r8a7791 ES1.0 Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

soc: renesas: Add R-Car RST driver 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.
