From 8ca7f4fe0733342c862b8585dd6eb6521b9bf533 Mon Sep 17 00:00:00 2001 From: "sean.wang@mediatek.com" Date: Tue, 16 Aug 2016 13:55:13 +0800 Subject: [PATCH] net: ethernet: mediatek: fix RMII mode and add REVMII supported by GMAC The patch fixes up the incorrect setup of reduced MII (RMII) on GMAC and adds the supplement for the setup of reverse MII (REVMII) on GMAC , and rearranges the error handling for invalid PHY argument.
