Use clk_disable_unprepare and clk_prepare_enable from the runtime PM callbacks, to fully gate|ungate clocks. Potentially this will save more power, depending on the clock tree for the current SOC.
The same patch has already been applied (I noticed and fixed it while doing unrelated code review).
pinctrl_pm_select_default_state(dev); - clk_enable(pl022->clk); + clk_prepare_enable(pl022->clk);
Someone should really make this check errors though! -------------- next part -------------- A non-text attachment was scrubbed...
