Which other drivers already contain this code? Are you planning on
converting them over to use these new functions? The code looks
familiar, so I assume it's just cut/paste from Tegra with some renames,
so I didn't read it through in detail.

I don't think those are the correct files for this code. Presumably
there's no reason at all why a pinctrl driver that doesn't require
CONFIG_GENERIC_PINCONF can't use these basic utility functions. Perhaps
add a new pinctrl-utils file?
