From dd13cbf7fc3cccd03bfa86d9292d9b960eb1fa70 Mon Sep 17 00:00:00 2001 From: Stefan Mavrodiev Date: Mon, 28 Aug 2017 09:32:42 +0300 Subject: [PATCH] ARM: dts: sun7i: Fix A20-OLinuXino-MICRO dts for LAN8710 From revision J the board uses new phy chip LAN8710. Compared with RTL8201, RA17 pin is TXERR. It has pullup which causes phy not to work. To fix this PA17 is muxed with GMAC function. This makes the pin output-low. This patch is compatible with earlier board revisions, since this pin wasn't connected to phy.
