zpa2326_suspend(9)

💤 zpa2326_suspend(9) — like, the Kernel API Manual page, bestie 💤

Okay so you found the zpa2326_suspend page in the Kernel API Manual and you're like "what does this even do" — don't worry, I got you. Grab a snack 🍓.

---

✨ NAME ✨

zpa2326_suspend — schedule a power down using the autosuspend feature of the PM layer. That's it, that's the whole vibe. It's giving "going to sleep but politely, on a schedule" 😴

---

🌸 SYNOPSIS 🌸

void zpa2326_suspend (struct iio_dev *indio_dev );

Yeah, it returns void — no return value, no drama, it just does the thing and dips 💅

---

🎀 ARGUMENTS 🎀

• indio_dev — the IIO device that's associated with the sampling hardware. Like, this is the device we're putting to bed. No cap.

---

🦋 DESCRIPTION 🦋

So here's the tea 🫖: the device gets switched to low power mode first — at the very start — so you're saving power even when the attached regulator is a "dummy" one. Literally saving energy regardless. Iconic behaviour, honestly 👑

💀 Real talk though: this page lives in ./drivers/iio/pressure, and the docs are stamped October 2026 — so if you're reading this from the future, hiii, hope the pressure sensor is thriving 🌈

Later bestie, go read the rest of the kernel docs — you're gonna slay 🫶✨
