From: Srinivas Kandagatla Date: Wed, 29 Jan 2014 16:19:44 +0000 (+0000) Subject: ARM: STi: STiH415: Add ethernet support. X-Git-Tag: dt-3.15~7^2~3 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c80fe3357fc13a4b5ecbb89a07d53c60f9df4b0a;p=karo-tx-linux.git ARM: STi: STiH415: Add ethernet support. This patch adds support to STiH415 SOC, which has two ethernet snps,dwmac controllers version 3.610. With this patch B2000 and B2020 boards can boot with ethernet in MII and RGMII modes. Tested on both B2020 and B2000.
