The reason some clocks were made optional in the binding was to account for the fact that depending on the SoC, some of the clocks might be fixed (ie not controlled by software). Given that the devicetree should represent the hardware, make all clocks required in the binding. Subsequent patches will make the DTS changes to specify fixed-clocks for the clocks that aren't controllable. Signed-off-by: Nícolas F. R. A.
