Subject: [PATCH v2 3/5] arm64: defconfig: Enable devfreq support for i.MX8MQ
Date: Wed, 17 Feb 2021 12:19:42 +0100	[thread overview]
Message-ID: <20210217111944.1416-4-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20210217111944.1416-1-martin.kepplinger@puri.sm>

From: Guido Günther <agx@sigxcpu.org>

This is needed to make DRAM frequency scaling via devfreq as used
on the Librem 5 and Librem 5 Devkit.

With the interconnect support enabled we now need imx devfreq on top
to make this work.
