STRUCT ZYNQ_PLATFORM_DATA(9)

💜 struct zynq_platform_data(9) 💜

okay bestie, so we're deep in the Kernel API Manual today (yes, that manual, the one with the good stuff) and the star of this page is struct zynq_platform_data — literally the zynq gpio platform data structure. it's the little bundle of info that tells the zynq GPIO driver what kind of beast it's dealing with. no cap, lowkey iconic. 🎀

---

✨ SYNOPSIS ✨

here's the whole shape of it, character for character, don't touch:

struct zynq_platform_data {
    const char *label;
    u32 quirks;
    u16 ngpio;
    int max_bank;
    int bank_min[ZYNQMP_GPIO_MAX_BANK];
    int bank_max[ZYNQMP_GPIO_MAX_BANK];
 };

that's it. that's the struct. gorgeous. 🦋

🌸 Members 🌸

okay so let's go member by member, because every single one matters, periodt:

• label — a string that gets stored in gpio->label. yes, it's literally just the name tag. it's giving "hello my name is" sticker energy 🫶
• quirks — Flags, and they're used to identify the platform. so like, which flavor of hardware are we on? that's what the flags spill 🍓
• ngpio — the max number of gpio pins. the absolute ceiling, bestie. the whole roster 💅
• max_bank — maximum number of gpio banks. how many little groupings we're working with 👑
• bank_min — this array represents bank's min pin. the lower edge of each bank, mapped out ⭐
• bank_max — this array represents bank's max pin. and here's the upper edge of each one. symmetric, slay 🌈

fr fr there are two arrays here and both are sized ZYNQMP_GPIO_MAX_BANK — do not forget that, it's in the synopsis for a reason 💀

and that's the page! this one lives over in ./drivers/gpio, and it was stamped October 2026 in the Kernel API Manual — so when you cite it, cite it cute. mwah, study hard bestie 💖✨
