STRUCT ZYNQ_GPIO(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct zynq_gpio(9) 💖

okay so this is a page from the Kernel API Manual, bestie, and it's literally all about struct zynq_gpio — the gpio device private data structure. yes. that's the whole vibe. let's get into it 🎀

✨ NAME ✨

struct zynq_gpio — the gpio device private data structure. that's it, that's the girl 💅

🌸 SYNOPSIS 🌸

here's the whole struct, copy it exactly, no cap:

struct zynq_gpio {
    struct gpio_chip chip;
    void __iomem *base_addr;
    struct clk *clk;
    int irq;
    const struct zynq_platform_data *p_data;
    struct gpio_regs context;
    spinlock_t dirlock;
 };

she's got seven members and every single one is doing her part 🫶

🦋 Members 🦋

okay so let's meet the cast, one by one, main character energy only:

  • chip — this is the instance of the gpio_chip. iconic. she's the actual gpio-ness of the whole thing.
  • base_addr — the base address of the GPIO device. like, where she lives 📍
  • clk — the clock resource for this controller. she needs her little heartbeat ⏰
  • irq — the interrupt for the GPIO device. when something happens, she says something 😭
  • p_data — a pointer to the platform data. pointers to pointers to vibes, iykyk
  • context — the context registers. memory of the moment, lowkey
  • dirlock — the lock used for direction in/out synchronization. she's the bouncer at the door keeping in and out from fighting 💀

your girl's whole friend group, plus the kernel file they all live in:

and that's the page, bestie!! 🧚 it came out of ./drivers/gpio, dated October 2026, and it's titled struct zynq_gpio(9) — so if you're ever lost in the kernel docs, just remember: she's the private data structure, she's got seven members, and she ate. periodt. 💜✨🌸
