From f2b1d2f94af887c91bb8a0cfb495e546331bc5ed Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 30 May 2018 17:25:13 +0200 Subject: soc: renesas: rcar-sysc: Provide helpers to power up/down CPUs Provide helpers to control CPU power areas from platform code, taking just a CPU index. This will avoid having to pass full CPU power area parameter blocks, and thus duplicating information already provided by SoC-specific SYSC drivers. This will be used on R-Car H1 only. Later R-Car generations rely on APMU/RST for CPU power area control.
