ASoC: sgtl5000: Improve VAG power and mute control

2019-10-11T16:35:54+00:00

commit b1f373a11d25fc9a5f7679c9b85799fe09b0dc4a upstream.

VAG power control is improved to fit the manual [1]. This patch fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot,
the VAG power remains off that leads to poor sound quality from line-in.

I.e. after boot:
  - Connect sound source to Line-In jack;
  - Connect headphone to HP jack;
  - Run following commands:
  $ amixer set 'Headphone' 80%
  $ amixer set 'Headphone Mux' LINE_IN

Change VAG power on/off control according to the following algorithm:
  - turn VAG power ON on the 1st incoming event.
  - keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In).
  - turn VAG power OFF when there is the latest consumer's pre-down event
    come.
  - always delay after VAG power OFF to avoid pop.
  - delay after VAG power ON if the initiative consumer is Line-In, this
    prevents pop during line-in muxing.

According to the data sheet [1], to avoid any pops/clicks,
the outputs should be muted during input/output
routing changes.

oem_table_id is 8 chars long, so we need to limit it, otherwise it

ALSA: hda/realtek - PCI quirk for Medion E4254

2019-10-05T13:12:16+00:00

[ Upstream commit bd9c10bc663dd2eaac8fe39dad0f18cd21527446 ]

The laptop has a combined jack to attach headsets on the right.
The BIOS encodes them as two different colored jacks at the front,
but otherwise it seems to be configured ok. But any adaption of
the pins config on its own doesn't fix the jack detection to work
in Linux. Still Windows works correct.

This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE,
which seems to register the microphone jack as a headset part and
also results in fixing jack sensing, visible in dmesg as:

-snd_hda_codec_realtek hdaudioC0D0:      Mic=0x19
+snd_hda_codec_realtek hdaudioC0D0:      Headset Mic=0x19

[ Actually the essential change is the location of the jack; the
  driver created "Front Mic Jack" without the matching volume / mute
  control element due to its jack location, which confused PA.

ALSA: firewire-tascam: check intermediate state of clock status and retry

2019-10-05T13:12:14+00:00

commit e1a00b5b253a4f97216b9a33199a863987075162 upstream.

2 bytes in MSB of register for clock status is zero during intermediate
state after changing status of sampling clock in models of TASCAM FireWire
series. The duration of this state differs depending on cases. During the
state, it's better to retry reading the register for current status of
the clock.

In current implementation, the intermediate state is checked only when
getting current sampling transmission frequency, then retry reading.
This care is required for the other operations to read the register.

This commit moves the codes of check and retry into helper function
commonly used for operations to read the register.

Lenovo ThinkCentre M73 and M93 don't seem to have a proper beep
although the driver tries to probe and set up blindly.
Blacklist these machines for suppressing the beep creation.

We don't need to deal with the unsol events for Intel chips that are
tied with the graphics via audio component notifier.  Although the
presence of the audio component is checked at the beginning of
hdmi_unsol_event(), better to short cut by dropping unsol_event ops.

ALSA: hda - Add a quirk model for fixing Huawei Matebook X right speaker

2019-10-05T13:12:09+00:00

[ Upstream commit a2ef03fe617a8365fb7794531b11ba587509a9b9 ]

[ This is rather a revival of the patch Tomas sent in months ago, but
  applying only with the quirk model option -- tiwai ]

Hard coded coefficients to make Huawuei Matebook X right speaker
work. The Matebook X has a ALC298, please refer to bug 197801 on
how these numbers were reverse engineered from the Windows driver

The reversed engineered sequence represents a repeating pattern
of verbs, and the only values that are changing periodically are
written on indexes 0x23 and 0x25:

0x500, 0x23
0x400, VALUE1
0x500, 0x25
0x400, VALUE2

* skipped reading sequences (0x500 - 0xc00 sequences are ignored)
* static values from reverse engineering are used

NOTE: since a significant risk is still considered, this is provided
as an experimental fix that isn't applied as default for now.  For
enabling the fix, you'll have to choose huawei-mbx-stereo via model
option of snd-hda-intel module.

If we get feedback from users that this works stably, we may apply it
per default.
