    detection.

  - wlf,micd-configs : Headset polarity configurations (generally used for

    detection of CTIA / OMTP headsets), the field can be of variable length

    but should always be a multiple of 3 cells long, each three cell group

    represents one polarity configuration.

    The first cell defines the accessory detection pin, zero will use MICDET1

    and all other values will use MICDET2.

    The second cell represents the MICBIAS to be used.

    The third cell represents the value of the micd-pol-gpio pin.
