Subject: [PATCH/RFC v2 12/12] drivers: sh: Disable PM runtime for multi-platform r8a7740 with genpd
Date: Tue, 16 Sep 2014 20:48:59 +0200	[thread overview]
Message-ID: <1410893339-6361-13-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1410893339-6361-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>

If the default PM domain using PM_CLK is used for PM runtime, the real PM
domain(s) cannot be registered from DT later.

Hence do not enable it when running a multi-platform kernel with genpd
support on an r8a7740. The R-Mobile PM domain driver will take care of
PM runtime management of the module clocks.

The default PM domain is still needed for:
  - platforms without genpd support,
  - the legacy (non-DT) case, where real PM domains may take over later,
    except for the C5 "always on" PM domain.
