STRUCT VOLTAGE_DEVICE(9)

💖 struct voltage_device(9) 💖

okay so bestie, welcome to the voltage_device era ✨ this is a Kernel API Manual page, and it's literally all about VM single input parameters. yes ma'am, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

struct voltage_device {
    u32 vm_map;
    u32 ch_map;
    u32 pre_scaler;
 };

---

👑 Members 👑

• vm_map — maps a channel number to a VM index. that's it, that's the job 💅
• ch_map — maps a channel number to a channel index. lowkey essential fr fr 🌟
• pre_scaler — the pre scaler value (it's 1 or 2), used to normalize the voltage output result. highkey important for the math 🧮✨

---

🦋 Description 🦋

so the structure provides the mapping between channel-number (0..N-1) and VM-index (0..num_vm-1) plus channel-index (0..ch_num-1), where N = num_vm * ch_num — the way that little equation ties it all together is iconic ngl 🔥

it also provides the normalization factor for the VM equation. slay, math queen 👑💖

🫶 quick reminder bestie: keep those member names exactly as written, no cap — they're u32 and they're not gonna spell themselves 💅

anywayyy, that's the whole read 🌈 run it, love it, cite it in your patch notes 💀 this page lives in ./drivers/hwmon, dated October 2026, and it's signing off with a little kiss from the kernel-source vibe check 🎀✨🦋 bye bestie 💖
