The driver looks pretty good now, thanks for addressing my comments to
previous version. There are still few issues remaining, though. Please see
my comments inline.

I don't see anything in binding documentation mentioning this compatible
value. Anyway, since there is already a generic binding for fixed rate
clocks, this shouldn't be needed at all.

This call could be dropped after moving to generic fixed rate clock
bindings.
