STRUCT GPIOCHIP_INFO(9)

💜 struct gpiochip_info(9) 💜

okay so bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, we're in kernel land now, buckle up 🎀 this page is all about struct gpiochip_info, and it's literally the lil info packet that tells you everything about a certain GPIO chip. iykyk 🌸

✨ NAME ✨

struct gpiochip_info — Information about a certain GPIO chip 🦋

---

🫶 SYNOPSIS 🫶

struct gpiochip_info {
    char name[GPIO_MAX_NAME_SIZE];
    char label[GPIO_MAX_NAME_SIZE];
    __u32 lines;
};

that's the whole vibe. three fields, no drama, main character energy 👑

💅 Members 💅

• name — the Linux kernel name of this GPIO chip ✨ like, its government name, the one the kernel actually calls it by.
• label — a functional name for this GPIO chip, such as a product number 📦 — and heads up, it may be empty (i.e. label[0] == ' ') 🫠 so don't be shocked when it gives you nothing.
• lines — number of GPIO lines on this chip 🔥 like, how many pins are on the roster fr fr.

ok and finally the cute sign-off 💌 — this lil page lives in ./include/uapi/linux, and it's dated October 2026 ⭐ so yeah, fresh off the press. periodt 💅
