Ok, sorry. You grouped it with MX6SL_PAD_AUD_MCLK__AUDIO_CLK_OUT,
which I also think should not be part of the hog group.

The hog group is better suited when there is no driver that can be
associated with that particular pin.

For the headphone GPIO detect, I think it makes sense to group it with
the other audio-related pinctrl pins.
