💖 of_get_regulator(9) — Kernel API Manual, bestie edition 💖

Okay so bestie, welcome to the of_get_regulator(9) page — it’s giving “find me the regulator device node by supply name” energy, and honestly? Iconic. Periodt. ✨

✨ NAME ✨

of_get_regulator — get a regulator device node based on supply name.

🌸 SYNOPSIS 🌸

struct device_node * of_get_regulator (struct device *dev , struct device_node *node , const char *supply );

🎀 ARGUMENTS 🎀

• dev — Device pointer for dev_printk messages. Yep, that’s the device pointer used for those messages. 🫶
• node — Device node pointer for supply property lookup. It’s the node pointer where the supply property gets looked up.
• supply — regulator supply name. Literally the supply name. 💅

🦋 DESCRIPTION 🦋

Extract the regulator device node corresponding to the supply name.

That’s the whole vibe: you hand it the supply name, and it extracts the matching regulator device node. No cap. 🌈

💜 RETURN 💜

Pointer to the struct device_node corresponding to the regulator if found, or NULL if not found.

So: found = pointer to the struct device_node, not found = NULL. Fr fr. 🎀
