Subject: [PATCH v5 8/8] drivers: sh: Disable PM runtime for multi-platform r8a7740 with genpd
Date: Mon, 17 Nov 2014 14:30:44 +0100 [thread overview]
Message-ID: <1416231044-1903-9-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1416231044-1903-1-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 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 genpd may take over later, except
for the C5 "always on" PM domain.
