STRUCT GPIO_EXTCON_DATA(9)

💅 struct gpio_extcon_data(9) — like, the whole vibe

okay bestie, welcome to the Kernel API Manual entry for struct gpio_extcon_data — no cap, it's just a lil container that holds the state for a super simple, GPIO-controlled extcon device. that's it. that's the whole thing. slay. ✨

🎀 NAME

struct gpio_extcon_data — a simple GPIO-controlled extcon device state container. literally just a struct whose whole job is holding onto the state of a GPIO-driven external connector. lowkey iconic of it. 💖

✨ SYNOPSIS

struct gpio_extcon_data {
    struct extcon_dev *edev;
    struct delayed_work work;
    unsigned long debounce_jiffies;
    struct gpio_desc *gpiod;
    unsigned int extcon_id;
    unsigned long debounce;
    bool check_on_resume;
 };

yes the indentation in the original is like that, we don't gatekeep. copy it exactly, bestie. 🫶

🌸 Members

• edev — the extcon device. you know, the actual extcon thang this whole struct is being the state container for. main character energy. 👑
• work — the work that gets fired by the interrupt. when the IRQ goes off, this is the delayed work that actually does the doing. 🔥
• debounce_jiffies — the number of jiffies to wait for the GPIO to stabilize. where does the number come from? the debounce value, obviously. iykyk. ⏳
• gpiod — the GPIO descriptor for this external connector. the actual pin, described. 🦋
• extcon_id — the unique id of the specific external connector. unique! specific! that's the whole point! 💅
• debounce — debounce time for the GPIO IRQ, measured in ms. milliseconds, not jiffies, don't mix them up bestie, that's how you get a vibe check failure. 😭
• check_on_resume — a boolean describing whether to check the state of the gpio while resuming from sleep. true = yes check it, false = don't. that's it. 🌈

👀 SEE ALSO

• Kernel file ./drivers/extcon/extcon-gpio.c — go read it, it's right there, it's giving source code realness. 📂
