In v5 I tried splitting the driver/bindings up into a basic part which
and a part which added the pin config stuff in the hope that the first
two patches could be applied first. This was not very well received, so
I merged it back.

I am aware that the binding looks quite different now, but this really
goes down to using the pinctrl bindings now.
