It was just a suggestion. It's not that obvious that the WD2 is part of
the PRTI6Q family for outsiders.

Yep, thanks for the link. So you override here the complete node since
it has the extact name. What do you want to change here and why didn't
you use phandle from the .dtsi?

I would appreciate this. It happens often that drivers are not mainlined
yet but patches are on the ML and on their way to mainline.

Yep, that looks a bit awkward.. What I wanted to say is to keep the
style over the DTs and don't mix them.

Pls, can you resend the patches with cc me or give me some pointers? So
we can give them another try.

I see, but I still prefer the "enable once" way since it is a bit more
straight forward. But it should be no blocker..

Adding the muxing later would be the better way.
