[PATCH ver.2 6.1.y 0/6] ASoC: codecs: es8326: fix support (backport from v6.6)

[kovalev]

Without these patches, all tested laptop models using the es8326 audio codec
have no sound from the speakers and headphones, and the headset microphone
does not work. Although the initialization of the sound card is successful.

--
ver.2:
drop a commit that does not affect the fix of functionality;
added an explanation that does not work on the current version of the kernel
without patches.
--

Patches have been successfully tested on the latest 6.1.86 kernel.

[PATCH 6.1.y 1/6] ASoC: codecs: ES8326: Add es8326_mute function

[kovalev]

From: Zhu Ning <zhuning0077@gmail.com>

Commit 083912c240de0c5f797da0443f5a99e87b75fcb3 upstream.

The internal analog power and hp Vref of es8326 should always be on to
reduce pop noise. The HP_VOL and HP_CAL are moved to es8326_mute function
so they are turned on at last and turned off at first.

Also, the calibration should be done manually once during start-up
to reduce DC offset on headphone.

[PATCH 6.1.y 2/6] ASoC: codecs: ES8326: Change Hp_detect register names

[kovalev]

From: Zhu Ning <zhuning0077@gmail.com>

Commit 4ddad00c609bdcd6635537d3acb9bd57a5fc79e6 upstream.

The old register naming method is confusing. The reg 0x57 decides
the default headset hardware connection type, and the reg 0xfb is
the headset detection status register, which changes during headset
insertion. Change the name to ES8326_HPDET_TYPE and ES8326_HPDET_STA.

[PATCH 6.1.y 3/6] ASoC: codecs: ES8326: Change Volatile Reg function

[kovalev]

From: Zhu Ning <zhuning0077@gmail.com>

Commit f1230a27c14b4d05e1d6af02be55c617b53728a4 upstream.

The new calibration and headphone detection function
require reading new volatile registers. Add them in
the volatile register function.

[PATCH 6.1.y 4/6] ASoC: codecs: ES8326: Fix power-up sequence

[kovalev]

From: Zhu Ning <zhuning0077@gmail.com>

Commit ac20a73d765c0374f5e7b5d0f2f43c4598d69c66 upstream.

Old power-up sequence causes large pop noise during start-up.
Using a new sequence instead.

Also, the registers are now reset to default value in suspend
function.

[PATCH 6.1.y 5/6] ASOC: codecs: ES8326: Add calibration support for version_b

[kovalev]

From: Zhu Ning <zhuning0077@gmail.com>

Commit 0663286e58e6f611f3578b5e63e1faa576d139fd upstream.

Version_b requires a new way of calibrating headset offset. A new
calibration function is added.

[PATCH 6.1.y 6/6] ASoC: codecs: ES8326: Update jact detection function

[kovalev]

From: Zhu Ning <zhuning0077@gmail.com>

Commit 04f96c9340463aae20d2511a3d6cb0b005b07d24 upstream.

The old jack detection function only supports fixed OMTP/CTIA
hardware connection. The new one supports auto OMTP/CTIA
headset detection
