Bug description:
[SRU Justifications]
========== linux-firmware ==========
[Impact]
Audio output doesn't work on Dell Bolan platforms with CS35L56 speaker
amplifiers
[Fix]
This requires following firmware blobs:
-
https://github.com/CirrusLogic/linux-firmware/commit/367fda8e56d7dda4c138438493e2bf6b9b92ce7b
which is not landed in linux-firmware mainline yet.
[Test Case]
1. Boot up the machine of Dell Bolan platform with CS35L56 speakers
2. Verify the sof-lnl-cs42l43-l0.tplg in in the
/lib/firmware/intel/sof-ipc4-tplg/
3. Verify with checking the output of `aplay -l` command with valid sof
output device. Should never be dummy output.
========== firmware-sof ==========
[Fix]
This requires following tplg file in firmware-sof
- sof-lnl-cs42l43-l0.tplg
upstream firmware-sof 2.10 will have this tplg file included.
[Test Case]
1. Boot up the machine of Dell Bolan platform with CS35L56 speakers
2. Verify with the linux-firmware with new CS35L56 amplifier support.
3. Verify with checking the output of `aplay -l` command with valid sof
output device. Should never be dummy output.
[Where problems could occur]
It only affects the Dell Bolan platforms with the new CS35L56 amplifier.
Should be low low risk of regression
