There was some recent thread about how the disabling of unused clocks

What recent thread and why would that be unsafe?  Any driver using a
clock or regulator ought to be making sure that the clock or regulator
is enabled before it tries to use it.  The worst that should happen is
that something gets the power bounced during boot which isn't the end of
the world.
