Why is this ST specific? PHYs being wakeup capable or not is independent 
of ST. If you want to or can use wakeup from the PHY, shouldn't that be 
a property in the PHY?

Seems to me you would want to define what all components are wakeup 
capable and then let the kernel decide which component to use. I'd think 
the kernel would prefer the PHY as that's closest to the wire and 
probably lowest power.

That's my 2 cents spending all of 5 minutes thinking about it. I'll 
defer to Russell and Andrew...
