    Subject[PATCH v4 0/4] ALSA: usb: UAC3 new features.
    Date
    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.
