[Bug 2077829] Re: Missing CS35L56 sof firmware for Dell Bolan platform

[Chris Chiu]

** Description changed:

+ [SRU Justifications]
+ 
+ ========== linux-firmware ==========
+ [Impact]
+ 
+ Audio output doesn't work on Dell Bolan platforms with CS35L56 speaker
+ amplifiers
+ 
+ [Fix]
  This requires following firmware blobs:
- * linux-firmware
-   - https://github.com/CirrusLogic/linux-firmware/commit/367fda8e56d7dda4c138438493e2bf6b9b92ce7b
- * firmware-sof
-   - sof-lnl-cs42l43-l0.tplg, not yet released.
+   - 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
