Hi Tony,

Each pin of OMAP requires a particular power to be enabled for the pin
to function (Ball Characteristics table from data manual). Is there a
plan how this is managed with pinctrl? Currently each driver needs to
make sure the correct regulators are enabled for the pins it uses, which
is platform specific and messy.

As a driver maintainer, I would wish that the pins would just get
enabled automatically when I call pm_runtime_get()...

 Tomi
