rza1_gpio_free(9)

okay bestie, welcome to the Kernel API Manual page for rza1_gpio_free(9) ✨ it’s giving “reset a pin,” and we’re keeping every single detail, no cap 💅

🌸 NAME 🌸

rza1_gpio_free — reset a pin

✨ SYNOPSIS ✨

void rza1_gpio_free (struct gpio_chip *chip , unsigned int gpio );

🎀 ARGUMENTS 🎀

• chip — gpio chip where the gpio sits on
• gpio — gpio offset

💅 DESCRIPTION 💅

okay so plot twist, bestie: freeing a gpio is surprisingly equivalent to requesting it 👀 Reset pin to port mode, with input buffer disabled. This overwrites all port direction settings applied with set_direction. like, all of them 😭 periodt.
