Why not just check the register map - can't the register be cached? If
that's not possible a comment would be good.

devm_clk_get()?

Shouldn't the provided return code be being used?

Why is the clock driver defaulting to enabling the clock, and if it
needs to shouldn't it be doing a prepere_enable() even if the enable
happens not to do anything to the hardware? Otherwise child clocks
might get confused.
The return value is also not being checked.
