Subject: [PATCH 0/3] ASoC: cs35l56: Change firmware filenames for SoundWire

Change the firmware filename format on SoundWire systems to
directly tie it to the physical amp it applies to. This is mainly
to decouple it from the ALSA prefix strings to avoid complications
when the SoundWire machine driver starts creating dailinks based on
SDCA Disco info instead of hardcoded match tables. It also avoids
errors from having to rename firmware files from a hardware-address
to a ALSA-prefix naming for Linux publication. There are already
published firmware files for the L56 B0 silicon so that has a fallback
scheme for backward compatibility which has been separated into its
own patch on top of the main change.

We'd like to get this into 6.16 so that the L63 support starts "clean"
with this new naming and we don't have to support one kernel version
with L63 using the old naming. Unfortunately we didn't manage to get
these patches through internal review and testing before the merge
window opened.
