This is a binding that has been defined for Samsung Common Clock Framework

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

Physically there is one clock controller (CMU) which has a lot of dividers, 
muxes and gates and so it is represented as a single device node.

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.
