Okay so welcome to the of_get_child_regulator(9) page from the Kernel API Manual, bestie! 💖

of_get_child_regulator — get a child regulator device node based on supply name. Periodt. 💅

---

🎀 SYNOPSIS 🎀

struct device_node * of_get_child_regulator (struct device_node *parent
       , const char *prop_name );

---

🌸 ARGUMENTS 🌸

• parent — Parent device node. The main character node, basically. 👑
• prop_name — Combination regulator supply name and "-supply". Yes, both of those things together, no cap. 🫶

---

🦋 DESCRIPTION 🦋

It literally traverses all child nodes, then extracts the child regulator device node that corresponds to the supply name. That's the whole vibe. ✨
