I didn't walk through the schematics and double-check the rails
personally, but the idea here is right. This matches the type of thing
we did for veyron, like in commit ca3516b32cd9 ("ARM: dts: rockchip:
Add pin names for rk3288-veyron-minnie")
I guess one minor nit (now that I look back on the veyron patch where
I mentioned it explicitly in the commit message) is that on the veyron
ones we sorted this down at the bottom with the other pinctrl stuff
instead of sorting it alphabetically with everything else. I'll let
Heiko say which he likes better.
I also notice for veyron that we had a second "ABI" exception for the
recovery mode pin, but I believe that goes through a different
mechanism now so we're good there.
Even though I didn't do a line-by-line review, I'll still give:

...though it's possible an "Acked-by" would be more in the spirit of
that? Not sure...
