pinctrl_register(9)

🎀 NAME 🎀

pinctrl_register — register a pin controller device. This is the Kernel API Manual entry for pinctrl_register(9), bestie, and it is lowkey giving “please read the warning first” energy.

✨ SYNOPSIS ✨

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

💅 ARGUMENTS 💅

• pctldesc — descriptor for this pin controller.
• dev — parent device for this pin controller.
• driver_data — private pin controller data for this pin controller.

🌸 DESCRIPTION 🌸

⚠️ Warning, fr fr: note that pinctrl_register is known to have problems as the pin controller driver functions are called before the driver has a struct pinctrl_dev handle. To avoid issues later on, please use the new pinctrl_register_and_init below instead. Periodt.
