[PATCH v3 5/6] ARM: dts: rockchip: enable gmac on RK3288 evb board
From: Roger Chen
Date: Mon Dec 29 2014 - 04:44:38 EST
enable gmac in rk3288-evb-rk808.dts
changes since v2:
1. add fixed regulator for PHY
2. remove power-gpio, reset-gpio, phyirq-gpio, pmu_regulator setting
3. add "snps,reset-gpio", "snps,reset-active-low;" "snps,reset-delays-us"
