So while this patch technically looks correct, I was wondering if we
should really explore the possibility of making the whole of sunxi
pinctrl DT controlled.
I brought this up a while ago, but people weren't overly enthusiastic
about it, though their argument weren't really convincing to me[1].

So:
As this "driver" here is basically a table linking GPIO bit settings
(the actual mux value) to names and every pin we care about needs to be
enumerated in the DT anyway, why not just add something like:
allwinner,pinmux = <4>;
to each pin(group) in the DT and get rid of this "driver" file here
entirely?
I'm open to that if you can use pinctrl-single which is in the kernel
for this purpose only, and is used with both OMAPs and HiSilicon.
I'm not open to that, and I'm getting tired of discussing it over and
over again. Andre, if you want to be convinced again, please read the
last discussion we had on this topic.
