I am not aware of any IO region to configure the PHY, although one may
exist. topcrm + 0x84 has two status bits reporting if USB and HSIC are
powered and out of reset. Nevertheless, the PHY feels distinct enough
from topcrm that it should have its own binding. The phy driver would
merely deassert the reset

This is the sort of thing that should be a child node of the syscon,
rather than integrated into the parent, given it consumes resources from
another feature of the syscon.

Ok, I'll go that route then

I think I can add the phy child to the binding later without breaking the ABI 
if I make it an optional member of the binding.
