Subject: [PATCH 00/16] SoundWire/ASoC: add SDW BPT/BRA support

This series adds support for SoundWire BPT/BRA. The change is mainly on
the SoundWire tree. It is better to go through the SoundWire tree with
Mark's Acked-by tag.

Pierre-Louis Bossart (16):
  Documentation: driver: add SoundWire BRA description
  soundwire: cadence: add BTP support for DP0
  soundwire: extend sdw_stream_type to BPT
  soundwire: stream: extend sdw_alloc_stream() to take 'type' parameter
  soundwire: stream: special-case the bus compute_params() routine
  soundwire: stream: reuse existing code for BPT stream
  soundwire: bus: add send_async/wait APIs for BPT protocol
  soundwire: bus: add bpt_stream pointer
  soundwire: cadence: add BTP/BRA helpers to format data
  soundwire: intel_auxdevice: add indirection for BPT send_async/wait
  ASoC: SOF: Intel: hda-sdw-bpt: add helpers for SoundWire BPT DMA
  soundwire: intel: add BPT context definition
  soundwire: intel_ace2x: add BPT send_async/wait callbacks
  ASoC: SOF: Intel: hda-sdw-bpt: add CHAIN_DMA support
  soundwire: debugfs: add interface for BPT/BRA transfers
  ASoC: rt711-sdca: add DP0 support
