zynq_gpio_dir_out(9)

✨ zynq_gpio_dir_out(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's called zynq_gpio_dir_out and it's honestly so straightforward it's giving "short and sweet main character energy".

---

🎀 NAME 🎀

zynq_gpio_dir_out — sets the direction of the specified GPIO pin as output. that's it, that's the vibe. ✨

---

🌸 SYNOPSIS 🌸

int zynq_gpio_dir_out (struct gpio_chip *chip , unsigned int pin , int state );

three args, one int coming back atcha. no cap. 🦋

---

💖 ARGUMENTS 💖

• chip — the gpio_chip instance we're working on. like, the whole chip you're poking at. 🔥
• pin — the gpio pin number within the device. gotta know which one, obviously. 📍
• state — the value that's gonna get written to the specified pin. literally the value, bestie. ⭐

---

🧚 DESCRIPTION 🧚

so here's the tea ☕ — this function sets the direction of the specified GPIO pin as output. then it configures the Output Enable register for that pin, and finally it calls zynq_gpio_set to set the state of the pin to whatever value you passed in. three little steps, one slay. 💅

like… it does exactly what it says on the tin. iconic behaviour honestly. 👑

---

🌈 RETURN 🌈

0 always. every single time. zero. nada. it's not giving suspense, and honestly? we respect the consistency. 🫶
