Hi Simon, Magnus,
When DT SYSC support was introduced in v4.7, legacy fallbacks were kept
to keep secondary CPUs working on R-Car H1, H2, and M2-W using old DTBs.
However, the time has come to drop these fallbacks, and clean up the
resulting code.
Most of this was written when I worked on DT SYSC support, but postponed
until the time was ripe. So basically I've been running this during the
last +2 years.
I avoided touching drivers/soc/renesas and arch/arm/mach-shmobile code
in the same patch. If you prefer some patches to be squashed, please
let me know.
Tested on Marzen (R-Car H1), Lager (R-Car H2), and Koelsch (R-Car M2-W).
Thanks!
