[RFC PATCH net-next 0/6] net: dsa: b53: mmap: Add bcm63xx EPHY power and reset control

[Kyle Hendry]

Some bcm63268 bootloaders hold the fast ethernet phys in reset 
causing an error when they're probed. The resets are controlled 
by a register in the gpio controller, and would need a minimal 
driver to set. However, that register also controls the 
power states of the EPHYs. I'm trying to implement both 
functionalities at the same time to make sure that they don't 
interfere with eachother. These patches allow control of the 
ephy register from the b53 switch driver. 

Is this the right place for this code, or should it be in a 
power domain? Should the resets be handled by a separate reset
controller?
