From 6de046eaa74a2a0fb68f1055a1d38bc93f4f16c7 Mon Sep 17 00:00:00 2001 From: Wenyou Yang Date: Thu, 20 Apr 2017 11:13:13 +0800 Subject: [PATCH] net: macb: Fix GMAC not work when enable DM_ETH Always search the PHY to determine the macb->phy_addr before using the PHY to fix "No PHY present" error. Fix the wrong test of the GMAC's phy interface mode, it should be PHY_INTERFACE_MODE_RGMII.
