Subject: [PATCH 00/12] soundwire: add multi-lane support

This series adds multi-lane support for SoundWire. We will get the lane
connection information from ACPI and use multiple lanes if the bandwidth
is not enough.

Bard Liao (10):
  soundwire: add lane field in sdw_port_runtime
  soundwire: mipi_disco: read lane mapping properties from ACPI
  soundwire: add lane_used_bandwidth in struct sdw_bus
  Soundwire: add sdw_slave_get_scale_index helper
  Soundwire: stream: program BUSCLOCK_SCALE
  Soundwire: generic_bandwidth_allocation: set frame shape on fly
  soundwire: generic_bandwidth_allocation: correct clk_freq check in
    sdw_select_row_col
  soundwire: generic_bandwidth_allocation: check required freq
    accurately
  soundwire: generic_bandwidth_allocation: select data lane
  soundwire: generic_bandwidth_allocation: add lane in sdw_group_params

Pierre-Louis Bossart (2):
  soundwire: stream: set DEPREPARED state earlier
  soundwire: generic_bandwidth_allocation: skip DEPREPARED streams
