From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Sasha Levin To: stable@vger.kernel.org, linux-kernel@vger.kernel.org Cc: Sascha Hauer , Shawn Guo , Sasha Levin Subject: [PATCH AUTOSEL 4.18 01/27] ARM: dts: imx53-qsb: disable 1.2GHz OPP Date: Mon, 22 Oct 2018 06:18:58 -0400 Message-Id: <20181022101924.40531-1-sashal@kernel.org> List-ID: From: Sascha Hauer [ 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.
