  hp-detect-gpios:
    description: 
      A GPIO spec for the external headphone detect pin. If jd-mode = 0, we
      will get the JD status by getting the value of hp-detect-gpios.

    description:
      A GPIO spec to control the external combo jack circuit to tie the
      sleeve/ring2 contacts to the ground or floating. It could avoid some
      electric noise from the active speaker jacks.
