Looks like the gpio reset driver might not make it into 3.12.

Now we have two options. 

1) leave the nop-phy driver as it is
2) get rid of using regulator framework for reset line and handle the reset
gpio directly in the nop-phy driver.

Is it already too late to get (2) into 3.12 if I send the patches in a day or 2?
