Is this intended? I just ask because it might change the boards behavior in case the boot loader touches one of the clocks from 1/4 and now they are disabled by the kernel. Best regards Dirk

Those always-on clocks need to be added into init_on array, this is to avoid confusion when we dump the clock tree, the result shows that some clocks are on but their enabled_count is 0.
