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.
