STRUCT RTD1625_GPIO_INFO(9)

🎀 struct rtd1625_gpio_info(9) 🎀

okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're in the kernel manual, everyone act normal 💅 this page is literally all about one lil struct and ngl it's kind of iconic.

---

✨ NAME ✨

struct rtd1625_gpio_info — the specific GPIO register info struct. that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

struct rtd1625_gpio_info {
    unsigned int num_gpios;
    unsigned int irq_type_support;
    unsigned int base_offset;
    unsigned int gpa_offset;
    unsigned int gpda_offset;
    unsigned int level_offset;
    unsigned int write_en_all;
 };

look at her. seven unsigned int fields, not one of them out of place. main character energy fr fr 👑

💖 Members 💖

okay so let's meet the cast, one field at a time:

• num_gpios — the number of GPIOs. that's how many of them there are. the count. the headcount. 🧚
• irq_type_support — the supported IRQ types. which interrupt types are getting the yes 👑
• base_offset — the offset for the GPIO controller register. like, where the controller register actually lives.
• gpa_offset — the offset for the GPIO assert interrupt status register. assert, as in it happened, say it with your chest 📣
• gpda_offset — the offset for the GPIO deassert interrupt status register. deassert, the opposite girlie, we love a balanced duo 🫶
• level_offset — the offset of the level interrupt status register. level-triggered, lowkey the chillest of the trigger types ✨
• write_en_all — the write-enable mask for all configurable bits. every configurable bit, enabled, together, as a treat 💜

---

🌈 SEE ALSO 🌈

• Kernel file ./drivers/gpio/gpio-rtd1625.c — the actual source, go read it, iykyk 🔥

bestie reminder: all those offsets are offsets, not addresses, not lengths, not vibes. don't be out here guessing 😭

and that's the page! 🍓 sign-off time: this lil writeup lives in ./drivers/gpio, dated October 2026, and it's the struct rtd1625_gpio_info(9) page — periodt 💅⭐
