[PATCH 0/4] ASoC: qcom: fixes for Click/Pop Noise

[Srinivas Kandagatla]

Click/Pop Noise was a long pending issue with WSA Codecs which are prone
to accumlate DC when ports are active but without any data streams.
There are multiple places in the current setup, where this could happen
in both startup as well as shutdown path.

This patches help fix those issues by making sure the PA is Muted/Unmuted
inline with the stream start/stop events.

Other than this there is a patch to fix DSP graph saturation issue as we never unload
playback graph before loading same graph.

Srinivas Kandagatla (4):
  ASoC: qcom: q6apm-lpass-dai: close graphs before opening a new one
  ASoC: qcom: sdw: do not restart soundwire ports for every prepare
  ASoC: codecs: wsa883x: mute/unmute PA in correct sequence
  ASoC: codecs: wsa881x: mute/unmute PA in correct sequence
