Bug description:
[SRU Justification]
[Impact]
Missing firmware for CS42L43 and CS35L56 for soundwire on Intel
LNL/ARL.
[Fix]
linux-firmware upstream commit 57077702373e ("linux-firmware: Add
firmware for Cirrus CS35L56 for Dell laptops").
[Test Case]
With successful loads, there should be dmesg txt showing the loaded
firmware, such as:
cs35l56 sdw:0:2:01fa:3556:01:2: DSP1:
cirrus/cs35l56-b0-dsp1-misc-10280c6b-spkid1-amp3.bin: v3.11.11
cs35l56 sdw:0:3:01fa:3556:01:0: DSP1:
cirrus/cs35l56-b0-dsp1-misc-10280c6b-spkid1-amp1.bin: v3.11.11
...
[Where problems could occur]
New hardware. No known problem yet.
[Other Info]
While this has been included in upstream tag 20240410, it's
automatically included in linux-firmware/oracular version
Ubuntu-20240730.git65c5d9b1-0ubuntu1, and therefore only Noble is
nominated for SRU.
