Subject: [PATCH] ARM: dts: sun6i: hummingbird: Add ethernet phy reset gpio properties
Date: Wed, 3 Dec 2014 15:19:13 +0800 [thread overview]
Message-ID: <1417591153-27177-1-git-send-email-wens@csie.org> (raw)
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.
