Subject: [PATCH AUTOSEL 4.14 01/15] ARM: dts: imx53-qsb: disable 1.2GHz OPP
Date: Mon, 22 Oct 2018 06:20:12 -0400 [thread overview]
Message-ID: <20181022102026.40869-1-sashal@kernel.org> (raw)
From: Sascha Hauer <s.hauer@pengutronix.de>
[ 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")
