Exactly what I was thinking.
It would be ideal if we could do this dynamically, so when a new
pinctr-single,bits is added we create a new object (after checking for
overlapping bits from previous objects).
If this is not possible we should have new property telling pinctrl-single how
many objects to create for one physical register (used only when
pinctrl-single,bit-per-mux is defined), something like:
pinctrl-single,bit-per-mux;
pinctrl-single,functions-per-register = <X>;
For sure we need to check here as well for overlaps in the bitfields...
