From e1391804967f38f64e6e73cab45da7fa5f451f6e Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 3 Dec 2014 15:19:13 +0800 Subject: [PATCH] ARM: dts: sun6i: hummingbird: Add ethernet phy reset gpio properties On the Hummingbird A31 board, the RTL8211E ethernet phy has its reset line connect to a gpio pin, instead of floating like on other boards. Add the stmmac properties for describing the reset gpio. The reset delays were taken from the RTL8211E datasheet.
