Well I was just thinking setting them up as separate driver
instances for the register ranges supporting pinconf and
not supporting pinconf. This combined with some pinconf
property parsed during pinctrl-single.c probe time allows
saving lots of unnecessary parsing of properties for
register ranges that don't support pinconf. At least for
omaps we have few hundred registers that don't support
pinconf, and then some separate random register that do.
