Hm depends on where the documentation hits I guess?
Such a generic cell count property has to be to the generic
pinctrl-bindings.txt document if I read it right.
Overall I guess this will be acceptable but you really need to
reuse some more code between this driver and pinctrl-single.c
if I read it right.
