STRUCT PINCTRL_PIN_DESC(9)

💅 struct pinctrl_pin_desc(9) — the Kernel API Manual, bestie edition ✨

Okay so real talk, this is a page from the Kernel API Manual (the 9 section, if you're keeping score), and it's about struct pinctrl_pin_desc. Grab a strawberry drink 🍓, we're doing this.

🌸 NAME 🌸

struct pinctrl_pin_desc — so basically, boards and machines out here providing information on their pins, pads, or other muxable units, and they do it in this struct. That's the whole vibe. 💅

---

✨ SYNOPSIS ✨

struct pinctrl_pin_desc {
    unsigned int number;
    const char *name;
    void *drv_data;
 };

Look at her. Three fields. Iconic. 👑

🎀 Members 🎀

• number — the unique pin number, pulled straight from the global pin number space. One number, one pin, no duplicates, periodt. 🔥
• name — literally just a name for this pin. That's it. That's the field. Give her a name, she deserves one. 🌸
• drv_data — driver-defined per-pin data. And here's the tea: the pinctrl core does not touch this. Not even a little. It's the driver's business, hands off. 🙈
