Thank you for your patch. There is something to discuss/improve.

You should constrain your clocks per variants. I doubt that they are
really so flexible/optional on each SoC... or maybe missing clocks are
result of unimplemented parts in the driver? But then this should not
really affect bindings. Bindings still should require such clocks. Your
DTS can always provide a <0>, if needed.
