2016-04-22soc: renesas: rcar-sysc: Add DT support for SYSC PM domainsGeert Uytterhoeven
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.

2016-04-22soc: renesas: Move pm-rcar to drivers/soc/renesas/rcar-syscGeert Uytterhoeven
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.
