    Subject[PATCH AUTOSEL 5.15] ASoC: Intel: bytcr_rt5640: Add quirk for the Advantech MICA-071 tablet
    Date
    From: Hans de Goede <hdegoede@redhat.com>

    [ Upstream commit a1dec9d70b6ad97087b60b81d2492134a84208c6 ]

    The Advantech MICA-071 tablet deviates from the defaults for
    a non CR Bay Trail based tablet in several ways:

    1. It uses an analog MIC on IN3 rather then using DMIC1
    2. It only has 1 speaker
    3. It needs the OVCD current threshold to be set to 1500uA instead of
    the default 2000uA to reliable differentiate between headphones vs
    headsets

    Add a quirk with these settings for this tablet.
