zpa2326_power_on(9)

✨ zpa2326_power_on(9) — the glow-up edition ✨

okay so bestie, we're deep in the kernel API manual for zpa2326_power_on(9) and honestly? this little function is giving "wake up babe, we have configuration to do" energy 💅 it lives in section 9 (kernel interfaces) and it's all about bringing the ZPA2326 pressure sensor up so you can actually talk to it. no cap.

---

🌸 NAME 🌸

zpa2326_power_on — literally powers the device on so you can configure it afterwards. that's the whole vibe 🫶

---

🎀 SYNOPSIS 🎀

int zpa2326_power_on (const struct iio_dev *indio_dev , const struct
zpa2326_private *private );

it takes two args and hands you back an int, periodt ✨

---

🦋 ARGUMENTS 🦋

• indio_dev — the IIO device that's besties with the sampling hardware 💖 like, this is the device we're actually powering on.
• private — the internal private state that goes with indio_dev. it's the backstage pass, iykyk 🙈

---

🔥 DESCRIPTION 🔥

so here's what goes down. sampling gets disabled first, which is genuinely important — the manpage says it prevents "strange things from happening in our back", and honestly? love that for us. no weird surprises, no chaos, just safe vibes 🧚

then the hardware FIFO content gets cleared. bye bye stale data, we don't know her 💀

and when it all works out? the device is left in the enabled state so you can keep configuring it. main character energy only 👑

---

⭐ RETURN ⭐

• 0 (zero) when it's a slay — success 💜
• a negative error code otherwise 😭 (that's the "nope, didn't work" signal, fr fr)

reminder bestie: zpa2326_power_on is the on switch and zpa2326_power_off is the off switch — don't mix them up, we've all been there 🙈
