Improve handling of always-on PM domains by using the GENPD_FLAG_ALWAYS_ON flag introduced in commit ffaa42e8a40b7f10 ("PM / Domains: Enable users of genpd to specify always on PM domains").

2017-04-07soc: renesas: rcar-sysc: Add support for fixing up power area tablesGeert Uytterhoeven1-0/+10
The same SoC may have different power areas, depending on SoC revision. One option is to use different sets of power area tables for each SoC revision. However, if the differences are small, it is much more space-efficient to have a single set of tables, and fix those up at runtime instead. Hence provide a helper to NULLify power areas that do not exist on some revisions (NULLified power areas are skipped during the registration phase), and support for an optional initialization callback to e.g. fix up power area tables.

2016-04-22soc: renesas: rcar-sysc: Add DT support for SYSC PM domainsGeert Uytterhoeven1-0/+53
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.
