Subject: [PATCH v3 3/5] arm64: defconfig: Enable devfreq support for i.MX8MQ
From: Guido Günther <agx@...xcpu.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.
