Merge branch 'mdio-gpio-next'
Florian Fainelli says:
====================
net: mdio-gpio: Use modern GPIO helpers
This patch series modernizes the mdio-gpio and makes it switch to the
latest and greatest API for manipulating GPIO lines, thus allowing
some simplifications in the driver.
====================
