Subject: [PATCH v2 12/16] ARM: dts: sun7i: Add pin muxing options for the GMAC
Date: Fri, 10 Jan 2014 15:00:13 +0800 [thread overview]
Message-ID: <1389337217-29032-13-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1389337217-29032-1-git-send-email-wens@csie.org>
The A20 has EMAC and GMAC muxed on the same pins.
Add pin sets with gmac function for MII and RGMII mode to the DTSI.
