Some devices have a 4-pin headset jack instead of 3-pin microphone jack. The new boolean nvidia,headset property tells that the Mic Jack represents the state of a headset microphone. This additional hardware description is needed because microphone detection procedure differs in a case of a 4-pin jack from a 3-pin jack.
