As suggested by Vinod, these patches are shared first - with the risk that they are separated from the actual DAI enablement, so reviewers might wonder why they are needed in the first place. For reference, the complete set of 90+ patches required for SoundWire on Intel platforms is available here: https://github.com/thesofproject/linux/pull/1692 changes since v1: Fix string allocation (only feedback from Vinod) Pierre-Louis Bossart (2): soundwire: intel: rename res field as link_res soundwire: intel: free all resources on hw_free() Rander Wang (3): soundwire: intel: add prepare support in sdw dai driver soundwire: intel: add trigger support in sdw dai driver soundwire: intel: add sdw_stream_setup helper for .startup callback drivers/soundwire/intel.c | 197 ++++++++++++++++++++++++++++++++++---- 1 file changed, 177 insertions(+), 20 deletions(-)
