From: Geert Uytterhoeven geert+renesas@glider.be

[ Upstream commit f5bbcd533a9d1af97b8a0862a421bb8455f1bf6d ]

Describe the GPIO used to reset the Ethernet PHY for EthernetAVB. This allows the driver to reset the PHY during probe and after system resume.

This fixes Ethernet operation after resume from s2ram on Salvator-XS, where the enable pin of the regulator providing PHY power is connected to PRESETn, and PSCI powers down the SoC during system suspend.

On Salvator-X, the enable pin is always pulled high, but the driver may still need to reset the PHY if this wasn't done by the bootloader before.

Inspired by patches in the BSP for the individual Salvator-X/XS boards by Kazuya Mizuguchi.
