I would ack that patch. I do believe that all NO_PAD_CTRL should
be replaced with whatever the register actually contains currently.
A "nop" patch that just makes things explicit.

Would you have a problem with that patch?

For your particular example of enet, I see no reason that the
pad settings should change when switching the mux from ENET to
gpio.


Btw, I do appreciate your looking at this board file.
Sorry, if I sounded rude.
