STRUCT ALTERA_GPIO_CHIP(9)

💅 struct altera_gpio_chip(9)

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is struct altera_gpio_chip, and honestly? she's giving very specific niche hardware energy and we're obsessed 🎀

---

🌸 NAME 🌸

struct altera_gpio_chip — no cap, that's the whole name, it just is 💅 (the og page keeps the description blank, so we're keeping it blank too, periodt)

---

✨ SYNOPSIS ✨

struct altera_gpio_chip {
    struct gpio_generic_chip chip;
    void __iomem *regs;
    raw_spinlock_t gpio_lock;
    int interrupt_trigger;
 };

like, look at her. four fields. no notes. 🔥

🦋 Members 🦋

• chip — the generic GPIO chip structure, aka her generic GPIO chip core. every icon needs a foundation bestie 🫶
• regs — the memory mapped IO address for the controller registers. literally where the controller keeps its stuff, mmkay 💖
• gpio_lock — a synchronization lock 🔒 so that new irq/set/get requests get blocked until the current one finishes. no cutting in line, she runs a very orderly queue ngl 😭
• interrupt_trigger — tells you the hardware configured IRQ trigger type: rising, falling, both, or high 🌈 (four vibes, pick one, iykyk)

👑 SEE ALSO 👑

• Kernel file ./drivers/gpio/gpio-altera.c — go read the source, it's right there, you got this 🧚

---

fr fr, every field, every trigger type, all of it is here — nothing skipped, nothing invented, we keep the facts and serve the vibe 💜
