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).

Sorry, didn't notice that.

Thanks!

Kind regards

      pinctrl_pm_select_default_state(dev);
-     clk_enable(pl022->clk);
+     clk_prepare_enable(pl022->clk);

Someone should really make this check errors though!
