[PATCH v4 0/4] Add support for audio on SDM845 SoC

[PATCH v4 0/4] Add support for audio on SDM845 SoC

[Rohit kumar]

This provides initial patchset to support audio on
Qualcomm Techonologies Inc. SDM845 SoC. Currently, it supports
audio playback/capture over Primary MI2S and Quaternary
TDM ports.

Changes since v3:
- Added Module_license in common.c
- Merged apq8096.c machine driver change with common api patch
- Addressed comments by Srinivas, Mark and Vinod.

Rohit kumar (4):
  ASoC: qcom: dt-bindings: Add sdm845 machine bindings
  ASoC: dt-bindings: Update dt binding name for apq8096
  ASoC: qcom: Add support to parse common audio device nodes
  ASoC: qcom: add sdm845 sound card support

[PATCH v4 3/4] ASoC: qcom: Add support to parse common audio device nodes

[Rohit kumar]

This adds support to parse cpu, platform and codec
device nodes and add them in dai-links. Also, update
apq8096 machine driver to use the common API.
