According to the figure 9.2(b) of the R-Car Series, 3rd Generation User’s
Manual: Hardware Rev. 0.80 the A2IRn and A2SCn power areas in R8A77970 have
the A3IR area as a parent, thus the SYSC driver has those parents wrong...

soc: renesas: rcar-rst: Enable watchdog as reset trigger for Gen2

2018-02-15T16:19:58+00:00

This patch allows for platform specific quirks as some of the SoC need
further customization for the watchdog to work properly, like for R-Car
Gen2 and for RZ/G.

soc: renesas: rcar-sysc: Mark rcar_sysc_matches[] __initconst

2018-02-12T12:50:37+00:00

rcar_sysc_matches[] is used only by rcar_sysc_pd_init(), which is
__init.  Hence mark rcar_sysc_matches[] __initconst.

This frees another 1764 bytes (arm32/shmobile_defconfig) or 1000 bytes
(arm64/renesas_defconfig) of memory after kernel init.

soc: renesas: rcar-sysc: Keep wakeup sources active during system suspend

2017-12-20T10:16:05+00:00

If an R-Car SYSC slave device is part of the CPG/MSTP or CPG/MSSR Clock
Domain and to be used as a wakeup source, it must be kept active during
system suspend.

Currently this is handled in device-specific drivers by explicitly
increasing the use count of the module clock when the device is
configured as a wakeup source.  However, the proper way to prevent the
device from being stopped is to inform this requirement to the genpd
core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.

Note that this will only affect devices configured as wakeup sources.
