It feels a little fragile to rely on the organisation of the clock tree
and the naming thereof. If the IP block is ever reused on an SoC with a
different clock tree layout then we have to handle things differently.
What do you suggest then?
I will admit that I don't have a better suggestion.

Without knowing which particular constraint on the mux parent clock we
care about it's difficult to suggest anything useful.
Well, I first made it into the mach- directory, and then was told to
move it in the driver itself, so we're kind of running out of options
:)
How about having a property in the clock provider node that forces a
specific value for the mux? I think that's generally the preferred solution
for any clock settings that go beyond what an OS can be expected to figure
out for itself.
