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;
  const char * name;
  int report;
  int invert;
  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

wake

enable as wake source

jack_status_check

callback function which overrides the detection to provide more complex checks (eg, reading an ADC).
