Thanks for reviewing the RFC patchset. Here is new patchset addressing all the comments from RFC. This patchset adds support for Qualcomm SoundWire Master Controller found in most of Qualcomm SoCs and WCD audio codecs. This driver along with WCD934x codec and WSA881x Class-D Smart Speaker Amplifier drivers is on DragonBoard DB845c based of SDM845 SoC. WCD934x and WSA881x patches will be posted soon. SoundWire controller on SDM845 is integrated in WCD934x audio codec via SlimBus interface. Currently this driver is very minimal and only supports PDM. Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team. TODO: Test and add PCM support. Thanks, srini Changes since RFC: - updated bindings as suggested to take care of more bus parameters. - fixed error code of snd_soc_dai_get_sdw_stream() dummy function. - Cleaned up driver to handle read/writes in same way without special casing. - removed unused defines Srinivas Kandagatla (4): soundwire: stream: make stream name a const pointer ASoC: core: add support to snd_soc_dai_get_sdw_stream() dt-bindings: soundwire: add bindings for Qcom controller soundwire: qcom: add support for SoundWire controller Vinod Koul (1): soundwire: Add compute_params callback .../bindings/soundwire/qcom,sdw.txt | 167 ++++ drivers/soundwire/Kconfig | 9 + drivers/soundwire/Makefile | 4 + drivers/soundwire/qcom.c | 919 ++++++++++++++++++ drivers/soundwire/stream.c | 12 +- include/linux/soundwire/sdw.h | 6 +- include/sound/soc-dai.h | 10 + 7 files changed, 1124 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/soundwire/qcom,sdw.txt create mode 100644 drivers/soundwire/qcom.c -- 2.21.0 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
