So since it's not named pinctrl-omap I guess you intend it
to be fully generic for simple muxes, which is nice!
If people start ACK:ing this I will be happy with it too,
because it's very easy to understand.

Do you want to evolve the patch for these features
or do you want to refactor it in later?
