I see, it's probably too late to change that then. Maybe if there is an Exynos6
this should be done differently though.

Some platforms just put device nodes for their clocks under the clock controller
node, which would have helped here. Another option would be to use
#clock-cells=<2>
and make the first cell the type of the clock, and the second one the number.
Also, if I understand things correctly, simple fixed rate clocks would normally
not go into the clock driver at all when they are not controller by it.
