In preparation of the upstream contribution of SDCA (SoundWire Device Class for Audio) ASoC codec drivers [1] [2], add regmap support SoundWire 1.2 MBQ support. The MBQ (Multi-Byte Quantity) registers need to be handled in a different way from regular 8-bit SoundWire registers, their main application is going to be for volume/gain controls.
The second patch was initially suggested for inclusion in the SoundWire tree, and was modified to add more background information on SDCA in the commit message as requested by Vinod Koul.
Is this targetted towards the sdw tree or regmap tree, I think it may have dependencies so sdw can be used.
It would be nice to mention these things here in cover
Changes since v1: Rebased on regmap tree (conflict with SPI stuff). Removed mod_devicetable.h header Removed -EOPNOTSUPP error codes, use -ENOTSUPP Added long description of SDCA Used FIELD_PREP/GET as suggested by Vinod Koul Added Bard Liao's Acked-by tag.
