pinctrl_gpio_set_config(9)

okay so this is pinctrl_gpio_set_config(9) from the Kernel API Manual — apply config to given GPIO pin 💅✨

🎀 NAME 🎀

pinctrl_gpio_set_config — apply config to given GPIO pin. That's the whole job, bestie. No cap. 🫶

✨ SYNOPSIS ✨

int pinctrl_gpio_set_config (struct gpio_chip *gc , unsigned int offset
, unsigned long config );

💅 ARGUMENTS 💅

• gc — GPIO chip structure from the GPIO subsystem. The chip struct in question. 🧚
• offset — hardware offset of the GPIO relative to the controller. Yes, that exact offset. 🔥
• config — the configuration to apply to the GPIO. The config being applied, periodt. 💖

🌸 DESCRIPTION 🌸

okay so listen closely: this function should ONLY be used from gpiolib-based GPIO drivers, if they need to call the underlying pin controller to change GPIO config (for example set debounce time). That's the lane. That's the whole assignment. 🚨

ONLY is doing a lot of work in that sentence, bestie. Like, do not wander into this function from random places. The manual said what it said. 💀✨
