clk_get() on a disabled clock node will return -EPROBE_DEFER, which can cause drivers to be deferred forever if such clocks are referenced in their devices' clocks properties. Update the various disabled external clock nodes to default to a frequency of 0, but don't disable them, to prevent this. Reported-by:

On R-Car H3, some power areas (e.g. A3VP) contain I/O devices, which are also part of the CPG/MSSR Clock Domain. 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. Signed-off-by:

Populate the SYSC PM domains from DT, based on the presence of a device node for the System Controller. 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. Signed-off-by:

Move the pm-rcar driver from arch/arm/mach-shmobile/ to drivers/soc/renesas/, and its header file to include/linux/soc/renesas/, so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car Gen3). 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. Add the missing #include <linux/types.h> to rcar-sysc.h, which was exposed by different include order. Signed-off-by:

The R-Car SYSC PM Domain driver has to power manage devices in power areas using clocks. To reuse code and to share knowledge of clocks suitable for power management, this is ideally done through the existing cpg_mssr_attach_dev() and cpg_mssr_detach_dev() callbacks. Hence these callbacks can no longer rely on their "domain" parameter pointing to the CPG/MSSR Clock Domain. To handle this, keep a pointer to the clock domain in a static variable. cpg_mssr_attach_dev() has to support probe deferral, as the R-Car SYSC PM Domain may be initialized, and devices may be added to it, before the CPG/MSSR Clock Domain is initialized. Dummy callbacks are provided for the case where CPG/MSTP support is not included, so the rcar-sysc driver won't have to care about this. Signed-off-by:
