| |
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.
