[Bug 2088403] Re: Missing CS42L43 sof firmware and alsa-ucm-conf for Dell Tarako platform

[Chris Chiu]

** Description changed:

  [SRU Justifications]
  
  ========== alsa-ucm-conf ==========
  [Impact]
  
  Audio output doesn't work on Dell Tarako platforms with Cirrus CS42L43
  codec
  
  [Fix]
  This requires following conf file in alsa-ucm-conf package:
    - /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
+ Need the https://github.com/alsa-project/alsa-ucm-conf/pull/465/commits/633a01b1e538ee9a577185f067bf2ca63696ada5 which is not yet landed upstream officially to fix the routing for internal speaker
  
  [Test Case]
  1. Boot up the machine of Dell Tarako platform with CS42L43 codec
  2. Verify the existence of /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
  3. Make sure the sof driver are loaded correctly. (tplg and Intel DSP FW are ready)
  4. Verify with checking the output of `amixer -c 0` command with valid Digital Speaker `Simple mixer control 'cs42l43 Speaker Digital',0`.
  
  [Where problems could occur]
  It only affects the Dell Tarako platforms with the new CS42L43 codec w/o other soundwire devices. Should be low low risk of regression
  
  ========== firmware-sof ==========
  
  [Fix]
  This requires following tplg file in firmware-sof
  - sof-lnl-cs42l43-l0.tplg and sof-arl.ri with sof-arl-cs42l43-l0.tplg
  upstream firmware-sof 2.11.x will have these tplg file included.
  
  [Test Case]
  1. Boot up the machine of Dell Tarako LunarLake and ArrowLake platform with cs42l43 internal speakers
  2. Verify with checking the output of `aplay -l` command with valid sof output device. Should never be dummy output.
  
  [Other Info]
  The name of sof-lnl-cs42l43-l0.tplg includes useful information which indicates that the topology is for for the cs42l43 codec connected to soundwire bus 0 w/o other soundwire devices connected on 1/2/3. It only affects the machines which has exactly the same soundwire configuration. The upstream commit of a newer version usually include the topology files for the new platforms or missing configuration on old platforms. It would be better to catch up with upstream to have these configuration which can support more configurations we could be missing in the future. The the addtional 0002-Add-SOF-v2.11.1-signed-Intel-binaries-for-MTL-LNL-AR.patch, it's required for each new Intel Platform and signed by Intel. In the case, the tplg file specify the `lnl`, a signed LunarLake DSP FW will be necessary. It would be better to have the Intel signed DSP FW up-to-date.
  
  [Where problems could occur]
  Although there're lots of new tplg files added, but they are mostly for missing configuration on old platforms or newly added for next-gen Intel platform. And they are specified for particular soundwire configurations which can hardly affect the existing machines. The risk for regression may come from sof-hda-generic-xxx.tplg which is for generic HDA. I'll consider it as low risk.
