STRUCT GPIO_KEYS_BUTTON(9)

🌸 NAME 🌸

okay so welcome to the struct gpio_keys_button(9) page in the Kernel API Manual, bestie ✨ this struct is literally all about configuration parameters — the NAME is struct gpio_keys_button — configuration parameters. periodt 💅

✨ SYNOPSIS ✨

       struct gpio_keys_button {
           unsigned int code;
         #ifdef CONFIG_GPIOLIB_LEGACY;
           int gpio;
         #endif;
           int active_low;
           const char *desc;
           unsigned int type;
           int wakeup;
           int wakeup_event_action;
           int debounce_interval;
           bool can_disable;
           int value;
           unsigned int irq;
           unsigned int wakeirq;
        };

🎀 Members 🎀

• code — input event code (KEY_*, SW_*) 💖
• gpio — -1 if this key does not support gpio 🦋
• active_low — true indicates that button is considered depressed when gpio is low
• desc — label that will be attached to button's gpio 🏷️
• type — input event type (EV_KEY, EV_SW, EV_ABS) ⭐
• wakeup — configure the button as a wake-up source 😴
• wakeup_event_action — event action to trigger wakeup
• debounce_interval — debounce ticks interval in msecs ⏱️
• can_disable — true indicates that userspace is allowed to disable button via sysfs 🫶
• value — axis value for EV_ABS
• irq — Irq number in case of interrupt keys ⚡
• wakeirq — Optional dedicated wake-up interrupt 🌙
