Subject: [PATCH v2] ARM: dts: imx53-qsb: disable 1.2GHz OPP
Date: Wed, 12 Sep 2018 08:23:01 +0200 [thread overview]
Message-ID: <20180912062301.3972-1-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20180910125056.30813-1-s.hauer@pengutronix.de>
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")
