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.

| | | | | | | | | | | | | | | | | | | | 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'. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

To ensure that the Tegra power domains (a.k.a. powergates) cannot be controlled via both the legacy tegra_powergate_xxx functions as well as the generic PM domain framework, add a bit map for available powergates that can be controlled via the legacy powergate functions. Move the majority of the tegra_powergate_remove_clamping() function to a sub-function, so that this can be used by both the legacy and generic power domain code.

On all R-Car SoCs, devices in the "always-on" PM Domain are part of the Clock Domain served by the CPG/MSSR or CPG/MSTP driver. Hook up the CPG/MSTP or CPG/MSSR Clock Domain attach/detach callbacks to enable power management using module clocks. Which callback to hook up depends on the presence of device nodes compatible with "renesas,cpg-mstp-clocks". This clears the path for a future migration from the CPG/MSTP to the CPG/MSSR driver on R-Car H1 and Gen2.

The actual power area hiearchy, and features of specific areas are obtained from tables in the C code. The SYSCIER and SYSCIMR register values are derived from the power areas present, which will help to get rid of the hardcoded values in R-Car H1 and R-Car Gen2 platform code later. Initialization is done from an early_initcall(), to make sure the PM Domains are initialized before secondary CPU bringup.

Rename it to rcar-sysc as it's really a driver for the R-Car System Controller (SYSC). Kill the intermediate PM_RCAR config symbol, as it's not user configurable anymore, and to prepare for SoC-specific make rules.
