Subject: [PATCH 3/4] drivers: sh: Stop using the legacy clock domain on ARM
Date: Tue, 16 Feb 2016 15:31:51 +0000	[thread overview]
Message-ID: <1455636712-3040-4-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1455636712-3040-1-git-send-email-geert+renesas@glider.be>

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").
