From 0a97aafe7fe50ed183e7fa0121fa7838e2e20306 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 18 Jun 2013 16:55:43 +0000 Subject: [PATCH 5/6] MIPS: BCM63XX: let board specify an external GPIO to reset PHY Some boards may need to reset their external PHY or switch they are attached to, add a hook for doing this along with providing custom linux/gpio.h flags for doing this.
