From ae765f3a8243faa39d4a32ba2baede638e40c768 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 11 Mar 2016 10:50:22 -0300 Subject: [PATCH] mx6slevk: Fix the power up of the Ethernet PHY GPIO4_21 is the LAN8720 power pin, not the LAN8720 reset pin. Fix that, so that we can have Ethernet functional again.
