Merge series "ASoC: meson: tdm fixes" from Jerome Brunet :

2020-07-30T20:00:36+00:00

This patcheset is collection of fixes for the TDM input and output the
axg audio architecture. Its fixes:
 - slave mode format setting
 - g12 and sm1 skew offset
 - tdm clock inversion
 - standard daifmt props names which don't require a specific prefix

Jerome Brunet (4):
  ASoC: meson: axg-tdm-interface: fix link fmt setup
  ASoC: meson: axg-tdmin: fix g12a skew
  ASoC: meson: axg-tdm-formatters: fix sclk inversion
  ASoC: meson: cards: remove DT_PREFIX for standard daifmt properties

ASoC: max98357a: move control of SD_MODE back to DAI ops

2020-07-21T20:37:51+00:00

Partially reverts commit 128f825aeab7 ("ASoC: max98357a: move control
of SD_MODE to DAPM").

In order to have mute control of max98357 from machine drivers, commit
128f825aeab7 ("ASoC: max98357a: move control of SD_MODE to DAPM")
moves the control of SD_MODE from DAI ops to DAPM events.  However, pop
noise has been observed on rk3399-gru-kevin boards due to this commit.

The commit 128f825aeab7 caused sequence of DAI clocks and SD_MODE
changed on rk3399-gru-kevin boards.

With the commit 128f825aeab7:
- SD_MODE will be set to 1 before DAI clocks start.
- SD_MODE will be set to 0 after DAI clocks stop.
As a result, pop noise.

Moves the control of SD_MODE back to DAI ops.  In the meantime, uses an
additional flag in DAPM event to provide chance of mute control for
machine drivers.

ASoC: max98357a: add compatible string for MAX98360A

2020-06-15T15:44:03+00:00

Maxim MAX98360A audio amplifier is functionally identical to MAX98357A.
Adds compatible string "maxim,max98360a" for driver reuse.

ASoC: max98357a: move control of SD_MODE to DAPM

2020-02-12T19:44:34+00:00

Some machine may share the same I2S lines for multiple codecs. For
example, mediatek/mt8183/mt8183-da7219-max98357 shares the same lines
between max98357a and da7219.  When writing audio data through the I2S
lines, all codecs on the lines would try to generate sound if they
accepts DO line.  As a result, multiple codecs generate sound at a
time.

Moves control of SD_MODE to DAPM so that machine drivers have chances
to manipulate DAPM widget to turn on/off max98357a.

ASoC: max98357a: use mdelay for sdmode-delay

2019-07-10T15:24:39+00:00

max98357a_daiops_trigger() is possible to be called in atomic context if
the .nonatomic flag is equal to 0 in the DAI links.

When cancel_delayed_work_sync() in max98357a_daiops_trigger() is called
in atomic context, kernel emits the following message: "BUG: sleeping
function called from invalid context".

According to the DT binding document, value less than or equal to 5ms of
sdmod-delay should be sufficient to avoid the pop noise.  Use mdelay
(i.e. busy loop) for such low delay should be acceptable.

ASoC: max98357a: avoid speaker pop when playback startup

2019-07-02T14:53:38+00:00

Loud speaker pop happens during playback even when in slience
playback. Specify Max98357a amp delay times to make sure
clocks are always earlier than sdmode on.
