STRUCT GPIO_KEYS_PLATFORM_DATA(9)

hey bestie!! welcome to the struct gpio_...latform_data(9) page from the Kernel API Manual 💖✨ we're talking about struct gpio_keys_platform_data, and it's lowkey the whole personality of the gpio_keys driver setup. it's giving kernel plumbing but make it cute 💅

✨ NAME ✨

struct gpio_keys_platform_data — platform data for gpio_keys driver. that's the vibe, no cap 🫶

🌸 SYNOPSIS 🌸

okay so here's the struct in all its main-character glory ✨:

struct gpio_keys_platform_data {
    const struct gpio_keys_button *buttons;
    int nbuttons;
    unsigned int poll_interval;
    unsigned int rep:1;
    int (*enable)(struct device *dev);
    void (*disable)(struct device *dev);
    const char *name;
};

🎀 Members 🎀

let's meet the members one by one, bestie — no skips, no cap 💅

• buttons — pointer to array of gpio_keys_button structures describing buttons attached to the device. that's the whole lineup, literally 👑
• nbuttons — number of elements in buttons array. the count, fr fr.
• poll_interval — polling interval in msecs — for polling driver only. do not forget the "only," bestie 😭
• rep — enable input subsystem auto repeat. auto repeat go brrr 🔥
• enable — platform hook for enabling the device. the "turn it on" hook ✨
• disable — platform hook for disabling the device. the "turn it off" hook 🫶
• name — input device name. iconic label energy 🎀

mwah 💋 this lil' page comes from ./include/linux, dated October 2026, and yes it's literally the struct gpio_...latform_data(9) page. bye bestie, go touch some kernel code 🫶✨
