[PATCH v2] ASoC: dt-bindings: cirrus,cs4270: Convert to dtschema
by Animesh Agarwal 11 Jul '24

Convert the Cirrus Logic CS4270 audio CODEC bindings to DT schema. Add missing va-supply, vd-supply and vlc-supply properties, because they are already being used in the DTS and the driver for this device.

Fix labeling of BOSS Katana ports
by GitHub pull_request - edited 10 Jul '24

10 Jul '24

alsa-project/alsa-ucm-conf pull request #430 was edited from aledomu: I'd like to rename the MIDI ports as well but I don't know how. If you can point me where I can learn about it, I'll be glad to do so and mark this PR as finished. I guess this fix works the same for all Katana models from all generations, but I don't have the PID available to enable it, nor the devices for testing. Edit: Didn't post the [`alsa-info.sh` output](https://gist.github.com/aledomu/ac3b2741ca2426bc6fbc057907ad0dab).
