STRUCT GPIO_PIN_RANGE(9)

💅 struct gpio_pin_range — Kernel API Manual bestie edition 💅

okay so this is the struct gpio_pin_range(9) page from the Kernel API Manual, and ngl it’s a tiny struct with main character energy. it’s literally the struct for a pin range controlled by a gpio chip. iconic. 🎀✨

✨ NAME ✨

struct gpio_pin_range — pin range controlled by a gpio chip. periodt. 💅

🌸 SYNOPSIS 🌸

       struct gpio_pin_range {
           struct list_head node;
           struct pinctrl_dev *pctldev;
           struct pinctrl_gpio_range range;
        };

🎀 Members 🎀

• node — the list hook for maintaining the set of pin ranges. it’s used internally, so it’s an inside-the-kernel kind of thing, fr fr. 🫶
• pctldev — a struct pinctrl_dev *: the pinctrl device that handles the corresponding pins. think of it as the pin-control bestie in charge. ✨
• range — a struct pinctrl_gpio_range: the actual range of pins controlled by a gpio controller. the real deal, no cap. 🔥
