🧚 __fwnode_iio_simple_xlate(9) — the Kernel API Manual, bestie edition 💖

okay so picture this: you're deep in the kernel, it's the Kernel API Manual, and you just need one tiny little translation done. that's literally this whole page. no cap. ✨

🌸 NAME 🌸

__fwnode_iio_simple_xlate — the little function that translates iiospec into the IIO channel index. that's it. that's the job. and it ate. 💅

---

💜 SYNOPSIS 💜

int __fwnode_iio_simple_xlate (struct iio_dev *indio_dev , const struct
       fwnode_reference_args *iiospec );

like, it takes two things and hands you back an int. iconic behaviour honestly. 🫶

---

🎀 ARGUMENTS 🎀

• indio_dev — a pointer to the iio_dev structure. your main character struct, your fave. 👑
• iiospec — the IIO specifier, exactly as found in the device tree. it walked in straight from the DT, no notes. 🌈

---

🦋 DESCRIPTION 🦋

so this is the simple translation function — hence the name, she's not trying to be mysterious — and she's perfect for the most 1:1 mapped channels in IIO chips. like, if your channels are a straightforward little one-to-one situation, this is your girl. 💖

now, don't go expecting her to do a whole background check on your data. she performs only one sanity check:

is the IIO index less than num_channels? 👀

and num_channels is the one specified in the iio_dev. that's the whole vibe check. one check, one pass/fail, no drama. periodt. 💀

okay bestie that's the page!! stay slay, may your indices always stay under num_channels, and remember where this came from: ./drivers/iio, October 2026, from your one and only Kernel API Manual 💅✨🎀
