CirrusLogic/CS8409: No headset mic device when plugged earphone jack when HDMI/DP is used on Dolphin platform

[You-Sheng Yang]

[SRU Justification]

[Impact]

When output device is set to HDMI/DP and headset plugged in, there is no
Headset device available in sound settings.

[Fix]

Proposed fix in
https://patchwork.kernel<email address hidden>/
, already accepted as
https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=94d508fa3186d0cbc63765aa94d5cf3bd847694c
. This also depends on two commits which already in mainline kernel that
refactor device init.

[Test Case]

1. Set output device to HDMI/DP
2. Plug headset
3. Check Sound settings for a new headset device

[Where problems could occur]

The last patch simply makes the onboard audio jack to use phantom jack.
No much potential risk introduced. The two prerequisites simplifies
init procedures and may need to receive some more stress tests
especially those for suspend/resume, plug/unplug.

[Other Info]

This is for the new oem Dolphin platform that is only available in
oem-5.13/oem-5.14 and impish. See bug 1939541.

========== original bug report ==========

[Steps to reproduce]
1. Check output device is HDMI/DP audio and it works
2. Plug headset
3. Check Sound settings for Input & Output

[Expected result]
Sound settings should have headset when plugging

[Actual result]
Sound settings has no headset

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-hwe-5.13/5.13.0-17.17~20.04.1 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
