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.

The patch looks good, but the timing is fairly late for merging to 4.15.
Isn't kbuild barfing all over these? Is that because of the cross-tree changes needed?
No, it's just local to the audio driver, plus a few include/linux/usb/*.h modification / addition. So there shouldn't be a big breakage in that regard.
The UAC3 gadget driver (which I sent to linux-usb mailing list) depends on a new audio-v3.h header which is a part of this patch.
So Felipe's tree will have dependency on Takashi's tree; and that's why kbuild notifies about build failure of UAC3 gadget driver.
OK, I see. I can prepare an immutable branch once when the patches are ready to merge.
