From: Tero Kristo <[email protected]> Current implementation will disable clocks in the order defined in clock34xx.h, at least DPLL4_M2X2 will hang in certain cases (and prevent retention / off) if clocks are not disabled in correct order. This patch makes sure the parent clocks will be active when disabling a clock.
