Subject[PATCH 4.9 126/171] ARM: dts: imx53-qsb: disable 1.2GHz OPP
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit eea96566c189c77e5272585984eb2729881a2f1d ]

The maximum CPU frequency for the i.MX53 QSB is 1GHz, so disable the
1.2GHz OPP. This makes the board work again with configs that have
cpufreq enabled like imx_v6_v7_defconfig on which the board stopped
working with the addition of cpufreq-dt support.

Fixes: 791f416608 ("ARM: dts: imx53: add cpufreq-dt support")
