The MIPI SoundWire Device Class standard will define audio functionality beyond the scope of the existing SoundWire 1.2 standard, which is limited to the bus and interface.
The description is inspired by the USB Audio Class, with "functions", "entities", "control selectors", "audio clusters". The main difference with the USB Audio class is that the devices are typically on a motherboard and descriptors stored in platform firmware instead of being retrieved from the device.
The current set of devices managed in this patchset are conformant with the SDCA 0.6 specification and require dedicated drivers since the descriptors and platform firmware specification is not complete at this time. They do however rely on the hierarchical addressing required by the SDCA standard. Future devices conformant with SDCA 1.0 should rely on a class driver.
This series adds support for the hierarchical SDCA addressing and extends regmap. It then provides 3 codecs for RT711-sdca headset codec, RT1316 amplifier and RT715-scda microphone codec.
Note that the release of this code before the formal adoption of the SDCA 1.0 specification was formally endorsed by the MIPI Board to make sure there is no delay for Linux-based support of this specification.
v2:
- rt715-sdca: Use rt715_sdca prefix to avoid compiling issue.
- rt715-sdca: Merge multiple mute/volume operation into single
mute/volume operation
- rt711-sdca: Initial ret = 0 as it could be used uninitialized.
Jack Yu (1): ASoC/SoundWire: rt715-sdca: First version of rt715 sdw sdca codec driver
Pierre-Louis Bossart (2): soundwire: SDCA: add helper macro to access controls regmap/SoundWire: sdw: add support for SoundWire 1.2 MBQ
Shuming Fan (2): ASoC/SoundWire: rt1316: Add RT1316 SDCA vendor-specific driver ASoC/SoundWire: rt711-sdca: Add RT711 SDCA vendor-specific driver
Hi Vinod/Mark,
Could we take this series into Vinod's tree with Mark's Acked-by? It failed to build on Mark's tree.
