I applied the patch and dropped you Reviewed-by tag. I think it depends on the 
taste of everybody how you prefer to structure this. I've also seen that on 
boards you care (mt8183 in that case) there a clocks that don't adhere to the 
criteria you mention here ;-)

Anyway many thanks for reviewing this and all the great work in general. 
Honestly I feel I didn't made justice by dropping your tag, but as you stated so 
explicitly... :)

Regards,
Matthias
