[PATCH v3 07/13] ARM: shmobile: R-Mobile: Use generic_pm_domain.attach_dev() for pm_clk setup

From: Geert Uytterhoeven
Date: Thu Sep 25 2014 - 12:29:08 EST


Use the just introduced genpd attach/detach callbacks to register the
devices' module clocks, instead of doing it directly, to make it
DT-proof.
