Bug description:
[SRU Justification]
[Impact]
Dolphin devices have CS8409 HDA Bridge connected to two CS42L42 codecs.
Codec 1 supports Headphone and Headset Mic. Codec 2 supports Line Out.
[Fix]
In order to support multiple CS42L42 codecs connected to a CS8409 HDA
Bridge, a changeset of 27 patches is proposed to
https://patchwork.kernel.org/project/alsa-devel/cover/[email protected]/
(now in linux-next), as well as two additional patches in
https://lore.kernel.org/lkml/[email protected]/
that fixes pop sounds at insertion of earphone jack and reboot. The
second patch of the latter changeset is on hold because of another fix
series that deprecates the reboot_notify callback of HD-audio by
forcibly doing runtime-suspend at shutdown.
A Ubuntu sauced patch is also added to enable the now stand alone
module snd-hda-codec-cs8409.
[Test Case]
Test on oem dolphin platform, as well as previous cs8409 platforms with
one single codec.
[Where problems could occur]
While this is the first platform we have multiple codecs connected to
a CS8409 HDA bridge, we may still have further stability or acoustic
quality issues as we had for previous cirrus platforms.
[Other Info]
This also fixes default sample rate problem that was previously fixed by
a oem-only package oem-fix-audio-cirrus-default-sample-rate.
