set_consumer_device_supply(9)

💅 set_consumer_device_supply(9) ✨

okay so bestie, welcome to the Kernel API Manual — yeah, the Kernel API Manual, we're doing kernel stuff today and honestly? iconic. this page is all about set_consumer_device_supply(9) and the way it just binds things together. let's get into it 🎀

---

🌸 NAME 🌸

set_consumer_device_supply — literally binds a regulator to a symbolic supply. that's the whole vibe. simple, elegant, slay 💅

---

✨ SYNOPSIS ✨

int set_consumer_device_supply (struct regulator_dev *rdev , const char
*consumer_dev_name , const char *supply );

yep, it returns an int. it takes three things. no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

okay so the three besties you're passing in:

• rdev — the regulator source. this is the origin point, the main character energy of the whole call 👑
• consumer_dev_name — the dev_name string for the device supply this applies to. so like, who is this supply for 🎀
• supply — the symbolic name for the supply. the cute little nickname, basically ⭐

---

🌈 DESCRIPTION 🌈

so here's what's happening: this lets platform initialisation code map physical regulator sources to symbolic names for supplies, for use by devices. lowkey a matchmaking service for hardware 💖

and the whole point? devices should use these symbolic names to request regulators — which means you avoid the need to provide board-specific regulator names as platform data. no hardcoded board names in your platform data, we simply don't do that anymore 🧚✨

---

🔥 RETURN 🔥

• 0 on success 🎉
• or a negative error number on failure 😭

that's it, that's the return contract, fr fr.

tiny reminder bestie 🫶 — the return is 0 on success or a negative error number on failure. don't be out here assuming positives mean anything nice, ok? 🙈

🎀 and that's the page 🎀

this lil beauty ships out of the ./drivers/regulator directory and it's stamped October 2026 — so bestie, it's from the future and it's still serving. mwah 💋✨🌸
