Ah, right.  I missed that the pins used for PHY strap options are
actually FEC pins.

How did you do that?  Since the pins will be switched between GPIO and
FEC functionality, they should not be defined in "hog" node any more.
It becomes difficult.

I plan to convert all the board files to DT and make the whole mach-mxs
DT only, and then more cleanup works can be proceeded.  It's much
preferred you can work on it yourself, if you can get to this soon.
Otherwise, I can remotely work it out with your help on testing? ;)
