STRUCT SND_SOC_JACK_GPIO(9)

💅 NAME

struct snd_soc_jack_gpio — the little struct that describes a GPIO pin for jack detection ✨ (yes, this is from the Kernel API Manual, we're being fancy today)

🎀 SYNOPSIS

struct snd_soc_jack_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

okay bestie, here's the cast of characters — every single field, no skips, no cap:

• idx — the gpio descriptor index within the function of the GPIO consumer device 🫶
• gpiod_dev — the GPIO consumer device itself, the main character 💅
• name — the gpio name. it also doubles as the connection ID for the GPIO consumer device's function name lookup — so it's doing two jobs, iconic 🔥
• report — the value you report when the jack is detected 🎀
• invert — report presence in the low state (yes, flipped, on purpose 🙈)
• debounce_time — debounce time, measured in ms ⏱️
• wake — enable this as a wake source 🌸
• jack_status_check — a callback function that overrides the detection so you can do more complex checks (eg, reading an ADC) — the overachiever of the group, honestly 👑

lowkey go read those two siblings too, they're giving family reunion energy 🧚

and that's the whole page bestie 💖 this little gem lives in ./include/sound, it's dated October 2026, and the whole thing is filed under struct snd_soc_jack_gpio(9) — slay, periodt 🎀✨
