pinctrl_gpi...ction_output(9)

💅 pinctrl_gpi...ction_output(9) — from the Kernel API Manual

okay so bestie, welcome to the group chat 💖 this is the manual page for pinctrl_gpio_direction_output — yes the header is doing that truncated thing (pinctrl_gpi...ction_output(9), iconic of it) but the full name is right there in the NAME section, we got you 🫶

---

✨ NAME ✨

pinctrl_gpio_direction_output — politely ask a GPIO pin to go into output mode 🎀

---

🌸 SYNOPSIS 🌸

int pinctrl_gpio_direction_output (struct gpio_chip *gc , unsigned int
offset );

like, that's the whole vibe. two args, one int back ✨

---

🦋 ARGUMENTS 🦋

• gc — the GPIO chip structure, straight from the GPIO subsystem 👑
• offset — the hardware offset of the GPIO relative to the controller 📍

---

💜 DESCRIPTION 💜

okay so here's the tea ☕ this function should *ONLY* be used from gpiolib-based GPIO drivers, as part of their gpio_direction_output semantics. that's the whole point of it, periodt 💅

and because we love a clear boundary: platforms and individual drivers shall *NOT* touch pin control GPIO calls. nope. not them. not ever. this is a driver-only zone 🔥

fr fr read that asterisk situation again — *ONLY* and *NOT* are not decorative, they're the whole rule 😭
