From 4d8f0825475ae7d48f4c5ed2fb85ea7e93212085 Mon Sep 17 00:00:00 2001 From: Byungho An Date: Sun, 7 Apr 2013 17:56:16 +0000 Subject: [PATCH] stmmac: modified pcs mode support for SGMII This patch modifies the pcs mode support for SGMII. Even though SGMII does auto-negotiation with phy, it needs stmmac_init_phy and stmmac_mdio_register function for initializing phy. Signed-off-by: Byungho An Signed-off-by: David S.
