ab8500_gpadc_parse_channel(9)

💅 ab8500_gpadc_parse_channel 💅

okay bestie, welcome to the Kernel API Manual entry for ab8500_gpadc_parse_channel(9) — yes that's a mouthful, no I will not be shortening it, it's iconic as-is. 🎀

---

✨ NAME ✨

ab8500_gpadc_parse_channel — process devicetree channel configuration 🦋

---

✨ SYNOPSIS ✨

int ab8500_gpadc_parse_channel (struct device *dev , struct
fwnode_handle *fwnode , struct ab8500_gpadc_chan_info *ch , struct
iio_chan_spec *iio_chan );

like, look at those four arguments. four. she's thorough. 💅

---

✨ ARGUMENTS ✨

• dev — pointer to the containing device, the whole reason we're here 🫶
• fwnode — the fw node for the channel we're configuring, that's the one we're reading from ✨
• ch — the channel info to fill in, she's empty right now and we're about to give her a whole personality
• iio_chan — the IIO channel specification to fill in, also getting filled in, also getting a glow-up 💖

---

✨ DESCRIPTION ✨

so the devicetree is gonna set up the channel for use with the specific device — that's the whole vibe — and it also defines usage for things like AUX GPADC inputs more precisely. like, way more precisely than you'd get otherwise. it's giving "the devicetree is the main character and everyone else is support cast" and honestly? periodt. 👑

ngl the whole point is that the config comes from the devicetree and lands in the structs you passed in, so by the time this returns your ch and your iio_chan are no longer empty little guys. 🌸
