Subject: [PATCH 0/3] soundwire: send multi sections in one BPT stream

Currently we send a BRA message with a start address with continuous
registers in a BPT stream. However, a codec may need to write different
register sections shortly. It makes more sense to send different
register sections in a BPT stream and no need to close/open the BPT
stream repeatedly.

This series depends on the "ASoC/soundwire: add fake BPT frame to align
Intel DMA buffer size" series. Sending it now to get more review time.

Bard Liao (3):
  soundwire: introduce BPT section
  soundwire: pass sdw_bpt_section to cdns BPT helpers
  soundwire: intel_ace2x: handle multi BPT sections
