: gpio name

struct snd_soc_jack_gpio - Describes a gpio pin for jack detection

: gpio number

: value to report when jack detected : report presence in low state : debouce time in ms : enable as wake source : callback function which overrides the detection to provide more complex checks (eg, reading an ADC).
