Please organize fixes separately from this patchset. You touch here
really too many subsystems and putting fixes in the middle of patchset
is another issue.

And drop this if:then:else. Binding should not enforce output clock
naming, because if this is fixed, then you do not need that property at
all. Things which are const are implied by compatible.
