ALSA: hda - Fix headphone noise on Dell XPS 13 9360

2016-06-06T23:12:31+00:00

[ Upstream commit 423cd785619ac6778252fbdb916505aa1c153959 ]

The headphone has noise when playing sound or switching microphone sources.
It uses the same codec on XPS 13 9350, but with different subsystem ID.
Applying the fixup can solve the issue.
Also, changing the model name to better differentiate models.

v2: Reorder by device ID.

ASoC: ak4642: Enable cache usage to fix crashes on resume

2016-06-06T23:12:28+00:00

[ Upstream commit d3030d11961a8c103cf07aed59905276ddfc06c2 ]

The ak4642 driver is using a regmap cache sync to restore the
configuration of the chip on resume but (as Peter observed) does not
actually define a register cache which means that the resume is never
going to work and we trigger asserts in regmap.  Fix this by enabling
caching.

ASoC: ak4642: Fix up max_register setting

2016-06-06T23:12:27+00:00

[ Upstream commit f8ea6cebcfa6499949392da71fc427567c9e5a0e ]

The max_register setting for ak4642, ak4643 and ak4648 are wrong, fix it.

According to the datasheet:
        the maximum valid register for ak4642 is 0x1f
        the maximum valid register for ak4643 is 0x24
        the maximum valid register for ak4648 is 0x27

The default settings for ak4642 and ak4643 are the same for 0x0 ~ 0x1f
registers, so it's fine to use the same reg_default table with differnt
num_reg_defaults setting.

[ Upstream commit 84add303ef950b8d85f54bc2248c2bc73467c329 ]

Phoenix Audio has yet another device with another id (even a different
vendor id, 0556:0014) that requires the same quirk for the sample
rate.

ALSA: hda - Fix subwoofer pin on ASUS N751 and N551

2016-05-17T17:43:09+00:00

[ Upstream commit 3231e2053eaeee70bdfb216a78a30f11e88e2243 ]

Subwoofer does not work out of the box on ASUS N751/N551 laptops. This
patch fixes it. Patch tested on N751 laptop. N551 part is not tested,
but according to [1] and [2] this laptop requires similar changes, so I
included them in the patch.

ALSA: hda - Fix broken reconfig

2016-05-17T17:43:07+00:00

[ Upstream commit addacd801e1638f41d659cb53b9b73fc14322cb1 ]

The HD-audio reconfig function got broken in the recent kernels,
typically resulting in a failure like:
  snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present

This is because of the code restructuring to move the PCM and control
instantiation into the codec drive probe, by the commit [bcd96557bd0a:
ALSA: hda - Build PCMs and controls at codec driver probe].  Although
the commit above removed the calls of snd_hda_codec_build_pcms() and
*_build_controls() at the controller driver probe, the similar calls
in the reconfig were still left forgotten.  This caused the
conflicting and duplicated PCMs and controls.

The fix is trivial: just remove these superfluous calls from
reconfig_codec().
