[PATCH v2] mdio_bus: Issue GPIO RESET to PHYs.

2017-04-20 Thread Roger Quadros
Some boards [1] leave the PHYs at an invalid state during system power-up or reset thus causing unreliability issues with the PHY which manifests as PHY not being detected or link not functional. To fix this, these PHYs need to be RESET via a GPIO connected to the PHY's RESET pin. Some boards have
