[PATCH 0/5] ASoC: rt286/rt298: Fixes for DMIC2 config and combo jack

[David Ward]

The last two patches in this series fix a longstanding issue that prevented
the ALC3263 codec from using a headset mic. This codec can be found on Dell
systems including the Latitude 13 7350, Venue 11 Pro 7140, and XPS 13 9343.
In fact, there is an ACPI quirk for the XPS 13 9343, which forces it to use
legacy HD Audio just to avoid this issue:

https://lore.kernel.org/alsa-devel/CAPeXnHv07HkvcHrYFmZMr8OTp7U7F=k_k=LPYnUtp89iPn2d2Q@mail.gmail.com/

This may allow that ACPI quirk to be removed. Either way, the other systems
mentioned above do not support this quirk and already use the ASoC driver,
so this fix is necessary for headset mic support on those systems.

Note: there is likely other handling for this codec that only exists in the
HDA driver, but which also belongs in the ASoC driver. Commit 394c97f824fa
("ALSA: hda/realtek - Change EAPD to verb control") describes an issue that
does not seem to be resolved in the ASoC driver, to give an example.


Other patches in this series are not specific to the ALC3263. These patches
set the correct combo jack configuration when headphones are inserted, and
fix a misaligned value set in the DMIC2 Configuration Default register.
