Hmm, only slightly related to this patch, mostly a generic
question to others: Do others have any mux registers with
status bits for things like PIN_CONFIG_POWER_SOURCE?
I could use PIN_CONFIG_POWER_SOURCE for controlling the PBIAS
for omap MMC. But there's also a status bit that needs to be
checked for that. I think there was some other similar mux
register for USB PHY that has a status register.
So I'm wondering should the checking for status bit be handled
in the pinctrl consume driver? Or should we have some bindings
for that?
Regards,
Tony
