      ASoC: qcom: lpass-cpu: Make I2S SD lines configurable · 4ff028f6
      Stephan Gerhold authored 
      The LPASS hardware allows configuring the MI2S SD lines to use
when playing/recording audio. However, at the moment the lpass-cpu
driver has SD0 hard-coded for mono/stereo (or additional fixed
SD lines for more channels).

For weird reasons there seems to be hardware that uses one of the
other SD lines for mono/stereo. For example, some Samsung devices
use an external Speaker amplifier connected to Quaternary MI2S.
For some reason, the SD line for audio playback was connected to
SD1 rather than SD0. (I have no idea why...)
At the moment, the lpass-cpu driver cannot be configured to work
for the Speaker on these devices.

The q6afe driver already allows configuring the MI2S SD lines
through the "qcom,sd-lines" device tree property, but this works
only when routing audio through the ADSP.

This commit adds a very similar configuration for the lpass-cpu driver.
It is now possible to add additional subnodes to the lpass device in
the device tree, to configure the SD lines for playback and/or capture.
E.g. for the Samsung devices mentioned above:

&lpass {
	dai@3 {
		reg = <MI2S_QUATERNARY>;
		qcom,playback-sd-lines = <1>;
	};
};

qcom,playback/capture-sd-lines takes a list of SD lines (0-3)
in the same format as the q6afe driver. (The difference here is that
q6afe has separate DAIs for playback/capture, while lpass-cpu has one
for both...)

For backwards compatibility with older device trees, the lpass-cpu driver
defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing.
This is equivalent to the previous behavior: Up to 8 channels can be
configured, and SD0/QUAT01 will be chosen when setting up a stream
with fewer channels.

This allows the speaker to work on Samsung MSM8916 devices
that use an external speaker amplifier.

      The lpass-cpu driver now allows configuring the MI2S SD lines
by defining subnodes for one of the DAIs.

Document this in the device tree bindings.

      Merge series "ASoC: rt5682: apply some refactors" from Tzung-Bi Shih <tzungbi@google.com>: · e8e7ef43
      Mark Brown authored 
      The series tries to refactor the coding style to follow most conventions.

The 4th patch converts pr_() to dev_().
(https://mailman.alsa-project.org/pipermail/alsa-devel/2020-March/164849.html)

The 6th patch changes the behavior a bit to restore its original intent.

Tzung-Bi Shih (6):
  ASoC: rt5682: simplify assertions
  ASoC: rt5682: fix space issues
  ASoC: rt5682: remove empty default case
  ASoC: rt5682: replace message printing from pr_() to dev_()
  ASoC: rt5682: remove duplicate rt5682_reset() calls
  ASoC: rt5682: remove unwanted btn_type assignment

      Merge series "SOF topology parsing updates" from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:

This series includes updates in the topology parser for DAIs
and their config.

The first three patches address the problem of sending the DAI
config to the DSP when there are multiple DAIs associated with
a DAI link.

The last patch deals with setting the default trigger order
for all links. Exceptions needed for HDA links are moved to
the DAI link fixup() callback.

Bard Liao (3):
  ASoC: SOF: topology: send ipc for all found DAIs in sof_set_dai_config
  ASoC: topology: set component dai_index to ipc dai config dai_index
  ASoC: SOF: topology: replace sof_link_hda_process by
    sof_set_dai_config

randerwang (1):
  ASoC: SOF: Intel: change trigger sequence to fix pop noise when
    stopping playback on sdw platforms
