[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:
    - 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.
  
+ [Where problems could occur]
+ It only affects the Dell Bolan platforms with the new CS35L56 amplifier. Should be low low risk of regression
+ 
  ========== 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
+ The sof-lnl-cs42l43-lp.tplg is from the upstream commit for production binaries, which includes different combinations of cs42l43(+cs35l56) on different platforms (MeterLake, LunarLake and newer ArrowLake). To prevent the future support problem of the different codec+amplifier configuration, and the production binaries are approved by the vendors, it should be low risk for regression.
