From 02e57b9d7c8ce9e403f15f48fb91dd6549aaf465 Mon Sep 17 00:00:00 2001 From: Giuseppe CAVALLARO Date: Fri, 24 Jun 2016 15:16:26 +0200 Subject: drivers: net: stmmac: add port selection programming In case of SGMII more, for example when a MAC2MAC connection is needed, the port selection bits (inside the MAC configuration registers) have to be programmed according to the link selected. So the patch adds a new DT parameter to pass the port selection and to programmed related PCS and CORE to use it. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S.
