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 3rd patch was initially suggested for inclusion in the SoundWire tree, and was modified to add more background information in the commit message as requested by Vinod Koul.
