In my opinion, apply the patch as is should be fine and we don't have any
build breakage. I think the change in each file is pretty trivial and won't
cause problem. otherwise, I will have to send patches for the conversion
in each file and then wait until all patches are merged. Then send another
patch to delete include/dt-bindings/phy/phy-miphy365x.h.

Axel
