xgpio_dir_out(9)

✨ xgpio_dir_out ✨

okay so bestie, welcome to the Kernel API Manual entry for xgpio_dir_out(9) — this is the glow-up function that tells a GPIO signal "you're an output now, diva 💅" and writes a value to it. it's giving very main character energy in gpio-xilinx.c, iykyk 🦋

🌸 NAME 🌸

xgpio_dir_out — sets the direction of the specified GPIO signal as output. that's it, that's the whole vibe ✨

🎀 SYNOPSIS 🎀

int xgpio_dir_out (struct gpio_chip *gc , unsigned int gpio , int val );

💖 ARGUMENTS 💖

• gc — pointer to the gpio_chip device structure. like, the whole chip's little passport 🫶
• gpio — the GPIO signal number. which specific lil signal we're talking to rn 🔥
• val — the value to be written to the specified signal. the actual tea being delivered ☕

🌈 DESCRIPTION 🌈

this function sets the direction of the specified GPIO signal as output. literally just flips it to output mode, no cap, that's the entire assignment 💅✨

⭐ RETURN ⭐

ok so the vibe check here is: if all GPIO signals of the GPIO chip are configured as input, it returns an error 😭. otherwise? it returns 0 and we celebrate 🎉
