intel_gpio_to_pin(9)

💅 intel_gpio_to_pin(9) — the kernel API manual, bestie edition 🎀

okay so picture this: you're deep in the kernel API manual (yes, that one), and the page is literally called intel_gpio_to_pin 💖 that's the whole vibe. it's a function, it translates things, and it's about to eat. let's get into it ✨

---

🌸 NAME 🌸

intel_gpio_to_pin — translate from GPIO offset to pin number 🔥 like, the whole personality of this function is conversion. it takes a GPIO offset and is like "ok but what's your pin number tho" 💅

---

✨ SYNOPSIS ✨

int intel_gpio_to_pin (const struct intel_pinctrl *pctrl , unsigned int
offset , const struct intel_community **community , const struct
intel_padgroup **padgrp );

look at that signature. four arguments, returns an int, no cap. she's got range 💜

---

🦋 ARGUMENTS 🦋

• pctrl — the pinctrl structure 🫶 that's your main character right there, the pinctrl struct itself.
• offset — the GPIO offset, straight from gpiolib 🌈 that's the number you're rolling in with.
• community — the community gets filled in here if it's not NULL 🎀 so if you pass a real pointer, she writes the community into it. if you pass NULL, she simply does not. iconic.
• padgrp — the pad group gets filled in here if it's not NULL ⭐ same energy, different pointer. NULL? cool, she skips it. not NULL? she's loading it up for you.

---

💀 DESCRIPTION 💀

okay so here's the lore 👑 when you come through gpiolib irqchip, the GPIO offset is not automatically translated to a pinctrl pin number 😭 like it just doesn't happen, nobody does it for you, you're on your own bestie.

that's where this function comes in 💅 you use intel_gpio_to_pin to find out the corresponding pinctrl pin. that's it, that's the job, and she does it beautifully 🌸

ngl this is the kind of function that exists purely because the automatic path ghosts you 🙈

---

🔥 RETURN 🔥

she gives you back:

• a pin number ⭐
• pointers to the community and pad group which the pin belongs to 🫶
• or a negative error code if the translation can't be done 💀 (translation said "no", and that's valid)
