Subject: [PATCH v2 6/6] drivers: sh: Disable PM runtime for multi-platform sh73a0 with genpd
Date: Wed, 14 Jan 2015 13:11:24 +0100	[thread overview]
Message-ID: <1421237484-16847-7-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1421237484-16847-1-git-send-email-geert+renesas@glider.be>

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 sh73a0. 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 genpd may take over later, except
    for the C5 "always on" PM domain.
