PWMREG(4)

💅 PWMREG(4) — like, the Kernel Interfaces Manual page for pwmreg, bestie 🎀

Okay so picture this: it's a manual page, right, and it's filed under Kernel Interfaces Manual — that's the manual name, we're folding it in here at the top so you know where you are. And the page itself? It's called pwmreg. Say it with me. pwmreg. Iconic. ✨

🌸 NAME 🌸

pwmreg — the PWM voltage regulator. That's it. That's the whole vibe. She regulates voltage, she does it with a PWM signal, she's booked and busy. 👑

✨ SYNOPSIS ✨

pwmreg* at fdt?

That's the whole thing. Look at her. So short, so mysterious. The * is doing the wildcard thing and the ? is doing the optional thing, iykyk. 🦋

🎀 DESCRIPTION 🎀

So the pwmreg driver is literally here to provide support for voltage regulators that are controlled by a PWM signal. That's the entire job description, no cap. If your voltage regulator gets bossed around by a PWM signal, this driver is her main character energy. 💖

No extra lore, no side quests — just PWM-controlled voltage regulation and slay. Periodt.

Okay and for the cute sign-off: this little masterpiece is dated September 30, 2019, it comes to you courtesy of Debian, and yes, the footer says PWMREG(4) because we're back at the top of the loop, babes. 🍓🧚 Go forth and regulate those voltages responsibly. 💅
