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.
v2:
- add 2 commits to fix the issue of starting streams simultaneously
Bard Liao (12):
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
SoundWire: pass stream to compute_params()
soundwire: generic_bandwidth_allocation: count the bandwidth of active
streams only
Pierre-Louis Bossart (2):
soundwire: stream: set DEPREPARED state earlier
soundwire: generic_bandwidth_allocation: skip DEPREPARED streams
