intel_pin_to_gpio(9)

✨ intel_pin_to_gpio 💅

okay so bestie, this is a page from the Kernel API Manual (section 9, the kernel-y one 🧚) and it's literally all about intel_pin_to_gpio — the little function that does the glow-up from pin number to GPIO offset. no cap, that's the whole vibe of it. 🦋

---

🌸 SYNOPSIS 🌸

int intel_pin_to_gpio (const struct intel_pinctrl *pctrl , int pin );

that's the whole signature, bestie — int in, int out, two args, iconic. 👑

---

🎀 ARGUMENTS 🎀

• pctrl — the pinctrl structure 🫶 (yes, the const struct intel_pinctrl * one, she's const so hands off)
• pin — the pin number, an int, just a number, that's her whole job 💅

---

💖 DESCRIPTION 💖

so what she does is take the pin number from that pinctrl and translate it into a GPIO offset. that's it. that's the function. lowkey obsessed with how straightforward she is ✨

---

🌈 RETURN 🌈

she hands you back a GPIO offset 💖 …or a negative error code if the translation can't be done 😭 (so like, vibe check your return value, fr fr — don't just assume it's a happy little offset).

ngl, a negative error code is not a GPIO offset, so check before you use it. 🚨

⭐ SEE ALSO ⭐

• the Kernel file ./drivers/pinctrl/intel/pinctrl-intel.c — she's the source file, the main character energy of this whole operation 🎀
• enum (anonymous)(9) 👀
• enum (anonymous)(9) 💀 (yes, she's listed twice — twice the anonymous enum, twice the mystery, iykyk)
• intel_gpio_to_pin(9) — the reverse-glow-up queen 🦋
• intel_gpio_add_pin_ranges(9) — the other sibling in this little pinctrl family 🌸

and that's the tea 🍓 — this page lives in ./drivers/pinctrl/intel, dated October 2026, from the Kernel API Manual, and she's called intel_pin_to_gpio(9). periodt. 💜✨
