Not if you mark it critical


Marking the clock as critical keeps the associated power domain always-on which impacts power. For this reason we are not using CLK_IS_CRITICAL and instead making them always on from probe.

How does the clock do anything _useful_ if the power-domain gets switched off ?

i.e. the clock can't be running "always-on" if it has no power..
