Support for Cirrus Logic audio solution CS42L45 with amplifiers on new Dell PTL platform

[Chris Chiu]

SRU Justification:

[Impact]
New Dell platform with CirrusLogic audio solution CS42L43+CS35L57/CS35L63 powered by Intel PantherLake will have no basic audio functions w/o Soundwire Driver Support.

<=============== alsa-ucm-conf ========================
Backport the patch firmware from CirrusLogic
f47b9418c81a ("ucm2: soundwire: cs42l45: Add support for CS42L45 codec")
2e090676c9a4 ("ucm2: Add setting LED Mode in SetLED macro")
7bab30e73569 ("ucm2: sof-soundwire: Update cs42l45 JackControls)
51bada5f0c1b ("ucm2: sof-soundwire: Simplify cs42l45 configs")

[Test Case]
1. Boot up the machine of new Dell Intel PantherLake platform with CirrusLogic CS42L43 + new amplifiers
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 codec+amplifier on PTL platform. No regression expected at the current stage.

This bug is awaiting verification that the linux-oem-6.17/6.17.0-1011.11 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.17' to 'verification-done-noble-linux-oem-6.17'.

Hi Kai-Chuan Hsieh,

Is "2e09067 ucm2: Add setting LED Mode in SetLED macro" really necessary?

If you look closer, the line:

just gets deleted anyway in "51bada5 ucm2: sof-soundwire: Simplify cs42l45 configs".

+ ]

Whats the point of this patch?

If you look more closely:

It moves the existing logic for If.1 into If.2, and adds completely new logic
for If.1.

Is this going to change behaviour of everyones Mute LEDS? How does alsa-ucm-conf
know to use this new If.1 or If.2 for existing behaviour?

I think this doesn't pass the "minimal patch" rules, and creates unnecessary risk.

Can you just delete the hunk from "51bada5 ucm2: sof-soundwire: Simplify cs42l45 configs".
instead, and delete "2e09067 ucm2: Add setting LED Mode in SetLED macro"
entirely?

When we backport patches to stable releases, they don't have to always be
straight cherry picks from upstream. Sometimes its better to modify patches so
that we only have the smallest fix possible. Within reason anyway.

That way it would be less likely to regress existing behaviour of the Mute LED.

PS, your patch format and naming is much better, well done!

Thanks,
Matthew

Hi Kai-Chaun,

Your noble debdiff contains an extra file "debian/patches/0001-ucm2-sof-soundwire-Add-support-for-CS42L43B-variant.patch".

This is not mentioned in d/changelog, and is not added to the series file. Since this bug is for a different chipset I just assumed you made a mistake and did not intend it to be there.

If you still need this file, file another LP bug and make another debdiff.

I have removed this file from the uploads.
