Libphy provides a standard set of helpers to access the MMD PHY
registers. Use those instead of relying on custom driver-specific
functions.

Hi Carlo
Maybe deja vu, but i thought a similar patch went by recently?
Anyway,

Hey Andrew,
> Maybe deja vu, but i thought a similar patch went by recently?
uhm, not from me for sure. There is a discussion going on about similar
stuff on the U-Boot ml, maybe you saw that?
Anyway, feel free to drop this if someone already fixed this.
Thanks,

Yes, probably that one.
Might be worth grepping of 0xd, 0xe, 0x0d, 0x0e, 13, 14, and see if
there are any more instances in PHY drivers.
