From 5b8524b03de813f027ac49bd3158a7789a4cc4a8 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Fri, 27 Feb 2015 17:39:49 +0000 Subject: brcm63xx: probe gpio controllers through DT Add a generic mmio gpio controller based driver and probe it through device tree. Use aliases for base calculation until we converted all users to device tree or named gpios. Convert bcm63xx_enet's ephy-reset gpio to use a named gpio. While at it, remove the duplicate reset gpio defintion for livebox.
