gpiochip_remove_pin_ranges(9)

🌸 NAME 🌸

okay bestie, welcome to the gpiochip_remove_pin_ranges(9) page from the Kernel API Manual — and this one is short but lowkey powerful: gpiochip_remove_pin_ranges removes all the GPIO <-> pin mappings. All of them. For real, no crumbs left. 💅✨

✨ SYNOPSIS ✨

She’s a void function with exactly one argument, no cap:

void gpiochip_remove_pin_ranges (struct gpio_chip *gc );

🎀 ARGUMENTS 🎀

• gc — the chip to remove all the mappings for. That’s the whole assignment: hand over the chip and every pin mapping attached to it gets cleared out. 🫶
