From 0d82c1831d3fe3cf53e6b8d0435ff6bd621e07d2 Mon Sep 17 00:00:00 2001
From: Valentin Raevsky <valentin@compulab.co.il>
Date: Sun, 20 Jul 2014 10:42:20 +0300
Subject: [PATCH 09/59] ARM: i.MX6: dts: Enable uart2 as a serial console
Enable ttymxc1 for use as a serial console:
1) Add the correct uart2 pinmux configuration.
2) Disable uart2 dte mode.
It allows running 'getty' and 'login' on the ttymxc1.
