From 3f75978b3742157853618c5c6dd4a5f49aa950b1 Mon Sep 17 00:00:00 2001
From: Shawn Guo <shawn.guo@linaro.org>
Date: Tue, 13 Aug 2013 14:10:29 +0800
Subject: [PATCH] ARM: imx6q: use common soc revision helpers
It calls imx_set_soc_revision() to set up soc revision in
imx6q_init_revision(), and replaces all the occurrences of
imx6q_revision() with common helper imx_get_soc_revision().
Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
