So from what I see now, it is most likely the easiest thing to just add
that wakeup to the phy driver I posted. Do you agree?
The whole idea of writing a seperate phy driver was to use the generic
phy framework
and most of the amxxxx devices have the same phy (eg am335x, am437x).
Now since the register is shared in am335x for phy_wkup (Not in the case
of am437x)
how are you planning to map it. I feel if omap_control_usb can delegate
the writes
to phy_wkup, phy_on and phy_off, it makes the life simpler.
that omap-control driver looks a little strange. It has a compatible
field saying ti,omap-control-usb and then it requires additionally a
ti,type property which should have been avoided.

ti,type property is to differentiate between usb2 and usb3 phy for a single soc.
for eg: OMAP5 has both usb2 and usb3 phy
