zpa2326_init...aged_trigger(9)

💖 zpa2326_init_managed_trigger — the glow-up guide 💖

okay so you're reading the Kernel API Manual (yes, that one, the kernel docs bestie) and you wanna know about zpa2326_init_managed_trigger. Say less, I got you. 🫶

✨ NAME ✨

zpa2326_init_managed_trigger — creates an interrupt driven / hardware trigger that lets the driver notify external devices that a new sample is ready. it's giving "hey everyone, fresh data just dropped" energy. 💅

🌸 SYNOPSIS 🌸

int zpa2326_init_managed_trigger (struct device *parent , struct iio_dev
*indio_dev , struct zpa2326_private *private , int irq );

like, four things go in, one int comes out. iconic signature behavior. ✨

🎀 ARGUMENTS 🎀

• parent — the hardware sampling device that indio_dev is a child of. it's the main character parent, fr fr. 👑
• indio_dev — the IIO device associated with the sampling hardware. this is the whole vibe of the sensor. 🦋
• private — internal private state related to indio_dev. the little secrets, lowkey. 🙈
• irq — optional interrupt line that the hardware uses to notify that new data samples are ready. negative or zero values mean no interrupts available — which means polling is required instead. so, no interrupt line? you're on poll duty, bestie. 😭

🔥 DESCRIPTION 🔥

only relevant when DT declares a valid interrupt line. that's it, that's the whole vibe check — no valid interrupt line in DT, no relevance. 💀

⭐ RETURN ⭐

zero when successful, a negative error code otherwise. slay when it works, sad little negative number when it doesn't. 💖

and that's the page!! 💜 brought to you straight out of ./drivers/iio/pressure, dated October 2026, and yeah the header and footer both say zpa2326_init...aged_trigger(9) because the terminal had to truncate it and honestly it's giving chaos but we move. 🧚 mwah, go read the source, ily. 🍓
