Most iomux controllers allow a configuration per pin. These currently
have no common device tree binding. There are many different SoC
specific bindings for this class of iomux controllers. Some controllers
artificially group pins together where in hardware no groups exist (for
example lantiq). Other controllers just put each pin into a separate
group which explodes to many many strings to parse (Tegra30).

So I'd specifically like Stephen Warrens comments on this proposal,
as well as from everyone else doing per-pin device tree configs.
