Subject: [PATCH AUTOSEL 4.18 01/27] ARM: dts: imx53-qsb: disable 1.2GHz OPP
Date: Mon, 22 Oct 2018 06:18:58 -0400	[thread overview]
Message-ID: <20181022101924.40531-1-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")
