Add the necessary sound card bits and some dts additions to enable sound over DisplayPort-over-USB-C, e.g. to a connected TV or monitor. The UCM files can be found here: https://gitlab.com/postmarketOS/pmaports/-/tree/master/device/testing/device-fairphone-fp5/ucm Two extra notes: 1. I don't quite understand whether the sound driver should have SoC-specific compatible or device-specific compatible. Some earlier patches by another author for a QCM6490 board and a QCS6490 board use device-specific compatible - but from what I can tell this is not how it's generally done for other sound drivers? 2. Unfortunately DisplayPort enablement itself for Fairphone 5 is not upstream yet. This is blocked by DSI display bringup upstream which is blocked by DSC 1:1:1 not being supported upstream yet and just working with a hacky patch. Nevertheless, DisplayPort audio was validated working with no additional sound-related changes so once DisplayPort gets enabled, sound should also just work upstream.
