🌸 SYNOPSIS 🌸

int of_genpd_add_device (const struct of_phandle_args *genpdspec ,
struct device *dev );

---

🎀 ARGUMENTS 🎀

• genpdspec — the OF phandle args you use to look up the PM domain, iykyk 🦋
• dev — the device getting added. that's the whole vibe.

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ — it looks up an I/O PM domain based on the phandle args you hand it, then adds the device to that PM domain. main character behavior honestly 👑

and if it goes wrong? it returns a negative error code on failure. no cap, that's your signal 😭

ngl, check that return value. negative error code = it didn't slay 💀
