[PATCH 0/7] ASoC/soundwire: add fake BPT frame to align Intel DMA buffer size

[Bard Liao <yung-chuan.liao@linux.intel.com>]

There is a constraint on Intel DMA buffer size that needs to be a
multiple of data block size. This series adds some fake BRA frames
to add some extra buffer size to meet the constraint.
The change is mainly on the soundwire tree. It would be better to go
through the soundwire tree.

Bard Liao (7):
  soundwire: cadence_master: make frame index trace more readable
  soundwire: only compute BPT stream in sdw_compute_dp0_port_params
  soundwire: cadence_master: set data_per_frame as frame capability
  soundwire: cadence: export sdw_cdns_bpt_find_bandwidth
  ASoC: SOF: Intel: export hda_sdw_bpt_get_buf_size_aligment
  soundwire: cadence_master: add fake_size parameter to
    sdw_cdns_prepare_read_dma_buffer
  soundwire: intel_ace2x: add fake frame to BRA read command
