omap_voltage_get_voltdata(9)

💅 omap_voltage_get_voltdata — Kernel API Manual ✨

okay bestie, so this one lives in the Kernel API Manual, and it's literally the little lookup goblin for OMAP voltages 🧚

---

🌸 NAME 🌸

omap_voltage_get_voltdata — the API that gets you the voltage table entry for a particular voltage 🎀

---

✨ SYNOPSIS ✨

struct omap_volt_data * omap_voltage_get_voltdata (struct voltagedomain
*voltdm , unsigned long volt );

like, that's the whole vibe. she takes two things and hands you back a pointer 💅

---

🦋 ARGUMENTS 🦋

• voltdm — pointer to the VDD whose voltage table has to be searched 👑 you're telling her which table to go digging in
• volt — the voltage to be searched in the voltage table 🔍 the actual number you're hunting for

---

💖 DESCRIPTION 💖

so here's the tea 🍓 this API searches through the voltage table for the required voltage domain and tries to find a matching entry for the passed voltage volt. If a matching entry is found, volt_data is populated with that entry — like, she found it and she's handing it over 🫶

⚠️ important caveat bestie: this API searches only through the non-compensated voltages in the voltage table. no cap, that's the whole scope. don't go expecting compensated stuff in there 💀

Returns a pointer to the voltage table entry corresponding to volt on success 🔥

Returns -ENODATA if no voltage table exists for the passed voltage domain, or if there is no matching entry 😭 (yes, both of those give you the same error, she's not gonna elaborate further)

aaaand that's the page, bestie 💜 this icon dropped under ./arch/arm/mach-omap2 in October 2026 — go forth and look up those voltages, ilysm 🎀✨
