This series add support for muxing individual pins within pin mux, rather than just whole groups. Mainly, I had two motivations here, one to avoid the need to add loads of groups containing individual pins and hardware that actually has some internal concept of groups of pins, and disambiguating that from individual pin muxing. I have marked it as RFC to just get peoples opinions at this stage, although it should be pretty well tested. Sorry about the amount of files touched in patch 2 it would be possible to drop it from the chain although it leaves the field rather inaccurately named. Also I have left all the existing code paths parsing all mux options as groups from DT, and added a new helper to unlock the pin based functionality this should ease the transition across.
