STRUCT SND_SOC_JACK_(9) ASoC STRUCT SND_SOC_JACK_(9)

NAME

struct_snd_soc_jack_gpio - Describes a gpio pin for jack detection

SYNOPSIS

struct snd_soc_jack_gpio {
  unsigned int gpio;
  unsigned int idx;
  struct device * gpiod_dev;
  const char * name;
  int report;
  int invert;
  int debounce_time;
  bool wake;
  int (* jack_status_check) (void *data);
};

MEMBERS

gpio
legacy gpio number
idx
gpio descriptor index within the function of the GPIO consumer device
gpiod_dev
GPIO consumer device
name
gpio name. Also as connection ID for the GPIO consumer device function name lookup
report
value to report when jack detected
invert
report presence in low state
debounce_time
debounce time in ms
wake
enable as wake source
jack_status_check
callback function which overrides the detection to provide more complex checks (eg, reading an ADC).
