> Backport new Intel soundwire drivers of the following
> ASoC: Intel: sof_sdw: Add new quirks for PTL on Dell with CS42L43 - kernel/git/broonie/sound.git - ASoC - (Upstreamed)
> ASoC: soc-acpi / SOF: Add best_effort flag to get_function_tplg_files op - kernel/git/broonie/sound… - (Upstreamed)
> ASoC: cs35l56: Use vendor-specific qualifier in firmware file search
> ASoC: cs-amp-lib: Support Dell SSIDExV2 UEFI variable

> <=============== firmware-sof ========================
> Add 2.14 tools and topology binaries for Intel MTL and newer targets · thesofproject/sof-bin at cdd3c8f
> 
> [Test Case]
> 1. Boot up the machine of new Dell Intel PTL Bolan platform with CirrusLogic CS42L43+CS35L56A
> 2. Open settings->Sound->Output Device and make sure it's not Dummy audio devices
> 3. Click test icon for basic audio output functions
> 4. Use `arecord` to record and play the recorded audio file with `aplay` for basic speaker/microphone functions.
> 
> [Where problems could occur]
> It adds the support for new CirrusLogic CS42L43+CS35L56A on PTL platform. No regression expected at the current stage.
