From: Shawn Guo <shawn.guo@xxxxxxxxxx> The RPM clocks are enabled/disabled through clk framework prepare/unprepare hooks. Without .is_prepared hook, those unused RPM clocks will not be disabled by core function clk_unprepare_unused_subtree(), because clk_core_is_prepared() always returns 0. Add .is_prepared hook to clk_ops and return the clock prepare (enable) state, so that those unused RPM clocks can be disabled by clk framework.
