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.
But back to the initial problem. I don't really like the idea of
touching in the control-module registers but others do it as well.
So the idea of a control driver doesn't sound that bad.
- an am335x-reset device
- a phy driver with a reference to that reset device.
- non-standard phy calls for power & wak eup on/off.
Let me think about it.
I think I buy it but give me a bitâ
