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.
