dev_pm_opp_get_supplies(9)

✨ dev_pm_opp_get_supplies ✨

okay so bestie, welcome to the dev_pm_opp_get_supplies(9) page 💖 this is a Kernel API Manual moment, and we are about to get your opp's supply info looking cute and correct 🎀

---

🌸 NAME 🌸

dev_pm_opp_get_supplies — literally just gets the supply information corresponding to an opp 🫶

---

🦋 SYNOPSIS 🦋

int dev_pm_opp_get_supplies (struct dev_pm_opp *opp , struct
dev_pm_opp_supply *supplies );

like, that's the whole vibe ✨

---

🎀 ARGUMENTS 🎀

• opp — the opp you want the voltage for, bestie 💅 this is the one we're pulling info from
• supplies — the placeholder where the supply information gets copied to 🍓

---

👑 RETURN 👑

so here's the tea ☕ if it fails you get a negative error number. if it works you get 0, after supplies has been set. periodt 💜

---

🌈 DESCRIPTION 🌈

this one is lowkey iconic because it works for devices with any number of power supplies ✨

⚠️ bestie, heads up: the caller must make sure the supplies array has space for each regulator. no cap, don't skip this part 😭
