From 98800eeb2244387e821f4af8d21ccf2deaf18da0 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Mon, 21 Aug 2017 23:02:32 +0800 Subject: [PATCH 003/146] net: stmmac: dwmac-sun8i: support RGMII modes with PHY internal delay Some boards uses a PHY with internal delay with an Allwinner SoC. Support these PHY modes in the driver. As the driver has no configuration registers for these modes, just treat them as ordinary RGMII.
