okay bestie, welcome to the Kernel API Manual ✨ — yes, that's the manual name, and yes, we're about to get into it. this little page is all about exynos_get_pmu_regmap_by_phandle, and honestly? it's giving "one job, does it well" energy 🎀

🌸 NAME 🌸

exynos_get_pmu_regmap_by_phandle — Obtain pmureg regmap via phandle 🦋

---

✨ SYNOPSIS ✨

struct regmap * exynos_get_pmu_regmap_by_phandle (struct device_node *np
, const char *propname );

like, literally that's the whole signature. two args, one regmap pointer, no cap 💅

---

🎀 ARGUMENTS 🎀

• np — Device node holding PMU phandle property 👑
• propname — Name of property holding phandle value ⭐

---

💜 DESCRIPTION 💜

okay so here's the vibe: this function goes and finds the pmureg regmap that was previously configured in probe, and then hands you back the regmap pointer. that's it. that's the whole personality 🫶

highkey the main character move here is "you set it up in probe, now come collect it" — iykyk 😭

---

🔥 RETURN 🔥

• A pointer to regmap if found 🔥
• or an ERR_PTR error value 💀

bestie please actually check it with IS_ERR() before you dereference anything, that's just self care 🙈
