[PATCH 3/4] drivers: sh: Stop using the legacy clock domain on ARM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled unconditionally
for Renesas ARM-based SoCs, the legacy clock domain is no longer used on
these SoCs.
Remove the related support code, and stop entering drivers/sh/ on ARM.

Notes:
  - This does break booting R-Car Gen2 boards using pre-v4.3 DTSes that
    don't have power-domains properties,
  - This may unbreak SuperH-based ARCH_SHMOBILE platforms, which were
    probably broken since v4.4 by commit 0ba58de231066e47 ("drivers: sh:
    Get rid of CONFIG_ARCH_SHMOBILE_MULTI").
