Hello,

this driver is probed only from device tree? If yes, it might be
sensible to specify the number of PWMs there and get it from there.
There doesn't seem to be a generic binding for that, but there are
several drivers that could benefit from it. (This is a bigger project
though and shouldn't stop your patch. Still more as it already got
Thierry's ack.)

Best regards
Uwe
