v4 Updates:
- Removes already applied patch from v2 of this patchset.
- Adds small patch to parse Feature Unit number of channels.
- Rebased onto latest linux-next tag as today.
Now that the UAC3 patch [1] has made it to linux-next I have some extra features to make a UAC3 devices fully work in Linux. Including Jack insertion control that I have put on top of this other patch [2] for UAC2. Also adding support for the UAC3 Mixer Unit which is most likely to appear in most headset type devices.
UAC3 devices also require to have a Basic Audio Device (BADD) in a separate config for which both Ruslan Bilovol and myself have submited different approaches[3][4]. After an ongoing discussion between Ruslan and myself we have decided that the patch from Ruslan[3] implements a simpler and yet more robust BADD driver.
All this features are tested with an actual UAC3 device that is still in development. For this patch series, only the legacy config (#1. UAC1/UAC2) and the UAC3 config have been tested. The BADD config will come in a different patch from Ruslan.
Based on linux-next tag: next-20180510

OK, now I applied all four patches. The patch 2 was queued to for-linus branch while others to for-next. The patch 4 was taken from the revised v4.
Thanks!
