-Subject: [PATCH 1/6] soc: renesas: rcar-sysc: Update power control flow for
- SYSCEXTMASK register
-
-On H3 v3.0, it can observe the system hang up after changing
-power domains many times (~2000 times) continuously.
-This occurs because there is conflict when changing state
-of power domains.
-
-To overcome this issue, power domain on/off control flow
-need to be updated. It needs to set/clear value of SYSCEXTMASK register.
-
-This patch is updated for above purpose.
