ALSA UCM2 sound device survey

MNT Reform
1

I’ve got a (mostly) complete ALSA UCM2 config written for my old imx8mq Reform, but I’m curious what the impact of this would be on users of other SoCs. From the .dts files it looks like the same config might also get applied to LS1028A and imx8mp.

If you have a non-imx8mq Reform and you want to help me figure this out, please post the output of these commands:

cat /proc/device-tree/model
cat /proc/asound/cards
amixer -c 0 controls

Here are the outputs for ls1028a, booted from a freshly obtained, unmodified system image:
