Recently released USB Audio Class 3.0 specification introduces many significant changes comparing to previous versions, like - new Power Domains, support for LPM/L1 - new Cluster descriptor - changed layout of all class-specific descriptors - new High Capability descriptors - New class-specific String descriptors - new and removed units - additional sources for interrupts - removed Type II Audio Data Formats - ... and many other things (check spec) It also provides backward compatibility through multiple configurations, as well as requires mandatory support for BADD (Basic Audio Device Definition) on each ADC3.0 compliant device This patch adds initial support of UAC3 specification that is enough for Generic I/O Profile (BAOF, BAIF) device support from BADD document.
