Can you further describe the scenario where this is a problem? Is it
some sort of clk that is enabled by default out of the bootloader and is
then configured to have an 'assigned-clock-parents' property to change
the parent, but that clk needs to be "enabled" so that the framework
turns on the parents for the parent switch?
