pinctrl_init_controller(9)

💅 pinctrl_init_controller(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're a kernel dev, you've got a shiny new pin controller, and it's just... sitting there. not initialized. embarrassing. 😭 that's literally where pinctrl_init_controller comes in — it's the glow-up routine for your pin controller device, and it lives right at home in the Kernel API Manual. periodt. ✨

🌸 NAME 🌸

pinctrl_init_controller — init a pin controller device 🫶

✨ SYNOPSIS ✨

struct pinctrl_dev * pinctrl_init_controller (const struct pinctrl_desc
*pctldesc , struct device *dev , void *driver_data );

🦋 ARGUMENTS 🦋

• pctldesc — the descriptor for this pin controller. like, the whole vibe sheet for your controller 📋
• dev — the parent device for this pin controller. gotta know where it belongs in the family tree 🌳
• driver_data — private pin controller data for this pin controller. it's giving "just between us" 🤫
