STRUCT ROCKCHIP_GPIO_REGS(9)

✨ struct rockchip_gpio_regs(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 — this is the page for struct rockchip_gpio_regs, and honestly? it's giving register map realness. it's a struct, it's all u32s, and every single one of them is a GPIO register on Rockchip SoCs. no cap. let's get into it 🎀

---

🌸 NAME 🌸

struct rockchip_gpio_regs — literally just the struct, that's it. the original page gives it a big fat dash and no description, and we respect that kind of main character energy 💅

---

✨ SYNOPSIS ✨

here's the whole thing, bestie, copied exactly so you can't mess it up:

struct rockchip_gpio_regs {
    u32 port_dr;
    u32 port_ddr;
    u32 int_en;
    u32 int_mask;
    u32 int_type;
    u32 int_polarity;
    u32 int_bothedge;
    u32 int_status;
    u32 int_rawstatus;
    u32 debounce;
    u32 dbclk_div_en;
    u32 dbclk_div_con;
    u32 port_eoi;
    u32 ext_port;
    u32 version_id;
 };

fifteen u32s. one struct. absolutely iconic 🔥

🦋 Members 🦋

okay so let's go member by member, no skips, no shortcuts 👑

• port_dr — the data register. that's the one, that's the data 💜
• port_ddr — the data direction register. it decides who's an input and who's an output. vibe check for pins ✨
• int_en — interrupt enable. turn it on, bestie 🫶
• int_mask — interrupt mask. the bouncer at the club, decides which interrupts actually get through 🚪
• int_type — the interrupt trigger type, like high, low, or edge trigger type. yeah it comes in flavors 😭
• int_polarity — interrupt polarity enable register. it's the "which way round tho" register 💅
• int_bothedge — interrupt bothedge enable register. both edges! not just one! generous queen 👑
• int_status — the interrupt status register. the receipts 💀
• int_rawstatus — and the relationship is exactly this: int_status = int_rawstatus & int_mask. raw status, masked. that's the whole tea 🍓
• debounce — enables debounce for the interrupt signal. so your signal stops being all jittery and chaotic 🙈
• dbclk_div_en — enables the divider for the debounce clock. divider: unlocked 🔥
• dbclk_div_con — the actual setting for the divider of the debounce clock. this is where you put the number, iykyk ⭐
• port_eoi — end of interrupt of the port. eoi = end of interrupt, say it with me 🎀
• ext_port — port data from external. looking at the pin from the outside like 👀
• version_id — the controller version register. every queen has a version tbh 🌈

lowkey a note: this whole page is straight out of the pinctrl corner of the kernel, so if you're poking at ./drivers/pinctrl/pinctrl-rockchip.h you're exactly where you're supposed to be 💖

and that's the whole page! sign-off time: this one comes from ./drivers/pinctrl, dated October 2026, and it's struct rockchip_gpio_regs(9) — slay, periodt, go read the registers 🦋💅
