From 3e6648c9c812f11117590ef846b205abd0224699 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 28 Aug 2013 14:08:22 -0500 Subject: serial: fsl-imx-uart: Cleanup duplicate device tree binding 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.
