This certainly makes things easier to mux :)
Have you verified that the registers are the same across all am335x
models and different revisions?
It used to be that different SoC revisions could have different
amount of registers and also different options in some cases.

You should only list the padconf mux registers here, no need to
list any of the controller registers.
