okay bestie, this is the Kernel API Manual page for of_devfreq_cooling_register(9), and yes the manual name is literally of_devfreq_cooling_register(9) too — folding it in right here so the top line doesn’t have to be all formal and repetitive. 💅

🎀 NAME 🎀

This function does exactly what it says on the tin: Register devfreq cooling device, with OF information. That’s the whole main-character job. ✨

💅 SYNOPSIS 💅

struct thermal_cooling_device * of_devfreq_cooling_register (struct
device_node *np , struct devfreq *df );

🫶 ARGUMENTS 🫶

Two arguments, both pointers, both important:

• np — pointer to OF device_node. That’s the OF device_node pointer, bestie. 🌸
• df — pointer to devfreq device. Yep, the devfreq device pointer. 🦋
