You forgot to check for the maximum possible value (510).
Good point!

Actually, we also have UDC specific 'min_power' field and a number
of other fields (does it really work w/o specifying 'clock' BTW?). I'd
suggest a larger function, assigning directly to the platform data
fields...
Is there a property already defined for the min_power?
The clock doesn't seem to be used at all. Or did I miss something?
