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).
