Subject: [PATCH 0/3] Add support for AW8898 Amplifier

Add devicetree bindings and a driver for the AW8898 Amplifier, and add
it to the devicetree for the Fairphone 3 smartphone.

Note, that this is the first audio driver I've worked on, so please
complain if something doesn't quite look right, it probably wasn't done
on purpose.

Unfortunately we can't wire up the full audio stack yet since the SoC
side is not upstream yet, the last revision from July 2024 can be found
here:
