Optional properties: - nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in +- nvidia,hd-no-invert : Do not invert headphone detect signal
We should use "hp" not "hd" to be consistent with other properties. Why can't we use the GPIO specifier's ACTIVE_LOW/ACTIVE_HIGH flag to represent the polarity of this signal?
