So you mean to drop patch 1 and 2 and keep the old style pinctrl
bindings around for the EMAC node?
I can certainly do this (if others agree), but didn't want to dodge a
more proper solution in the first place.
Another alternative would be to squash the functionality of patch 1
directly into sun8i_emac.c, so without the moving to pinmux.c. This
would mean dropping patch 1/6 and just having a fix for the sun8i_emac.
Let me know what's the preferred solution here.
Cheers,
Andre.
