pinctrl_register_and_init(9)

💅 pinctrl_register_and_init(9) — like, the Kernel API Manual page, bestie ✨

okay so we're in the kernel API manual today and this one is called pinctrl_register_and_init — it does exactly what it says on the tin: registers and inits a pin controller device. two jobs, one function, main character energy fr fr 🎀

---

🌸 NAME 🌸

pinctrl_register_and_init — register and init pin controller device. that's it, that's the whole vibe 💖

---

✨ SYNOPSIS ✨

int pinctrl_register_and_init (const struct pinctrl_desc *pctldesc ,
struct device *dev , void *driver_data , struct pinctrl_dev **pctldev );

like yes she takes four args and returns an int, no cap 🫶

---

🦋 ARGUMENTS 🦋

• pctldesc — the descriptor for this pin controller. it's giving "the blueprint" tbh 💅
• dev — the parent device for this pin controller. every icon needs a parent, ykyk 👑
• driver_data — private pin controller data for this pin controller. lowkey just yours, keep it safe 🙈
• pctldev — the pin controller device. this is where she ends up living 🌈

---

🍓 DESCRIPTION 🍓

okay so listen, this is the important part and i need you to actually read it bestie: you still have to call pinctrl_enable manually after this — like, once the driver is ready. so don't @ me when nothing works because you skipped the second step 😭 this function does not enable it for you, periodt.

⚠️ real talk: pinctrl_enable still needs to be manually called after this, once the driver is ready. no automatic enable, no shortcuts, no exceptions 💀

and that's the tea, bestie 🧚 this page lives in the kernel tree under ./drivers/pinctrl, and it's dated October 2026 — so yeah, future slay 💅✨ bye, love u, go call pinctrl_enable 🫶
