[PATCH 1/2] serial: fsl-imx-uart: Cleanup duplicate device tree binding

From: Kumar Gala
Date: Wed Aug 28 2013 - 15:08:34 EST


We had two bindings for the same serial device, it looks like the one in
tty/serial/fsl-imx-uart.txt is the more up to date one so go with it and
merge a few things about the use/need for aliases in from
serial/fsl-imx-uart.txt.
