From db40f15b53e430d697efa6229b1bced30894d0d3 Mon Sep 17 00:00:00 2001 From: David Wu Date: Thu, 10 Aug 2017 22:01:08 +0800 Subject: [PATCH] ARM: dts: rk3228-evb: Enable the integrated PHY for gmac This patch enables the integrated PHY for rk3228 evb board by default. To use the external 1000M PHY on evb board, need to make some switch of evb board to be on. Signed-off-by: David Wu Reviewed-by: Florian Fainelli Signed-off-by: David S.
