OK, I have applied this, BUT:

All of this exist in the generic pinconf library nowadays.

How about cooking a patch that converts the lantiq driver
to just use that? It'll be pretty straight forward I think.

I mean you convert it to use the generic pinconf internally,
the DT representation we'll have to live with.

See for example the new drivers that are boiling in
-next. All use generic pinconf I think. The parameter to
set a pin as output was added for the abx500 driver
this cycle.
