of_match_node(9)

✨ of_match_node(9) — like, the kernel API manual page, bestie ✨

okay so real talk, this is of_match_node(9) from the Kernel API Manual and it's genuinely one of those little utility functions that holds the whole device-matching situation together. lowkey iconic. let's get into it 💅

---

🌸 NAME 🌸

of_match_node — tells you whether a device_node has a matching of_match structure. that's it, that's the whole job, and she does it flawlessly 🫶

---

🎀 SYNOPSIS 🎀

const struct of_device_id * of_match_node (const struct of_device_id
*matches , const struct device_node *node );

like, copy that exactly, no cap, don't retype it from memory 🙈

---

💖 ARGUMENTS 💖

• matches — the array of of device match structures to search through. this is the list you're checking against, bestie, the whole roster 💅
• node — the of device structure you're matching against. the one on trial, basically 🔥

---

🦋 DESCRIPTION 🦋

so here's the tea: this is a low level utility function used by device matching. that's the vibe — it's one of the little building blocks other matching code leans on. not the main character, more like the best friend who makes the main character's whole plot work 😭💜

ngl it's described as "low level," so if you're in userspace wondering about it... you're not the target audience, babe 🌈

okay this list is LONG and we are not skipping a single one, because every single one of these is part of the family 🎀 and yes, the kernel file is ./drivers/of/base.c — that's where she lives 🏡

and that's the whole page, bestie!! sign-off time: this little beauty comes from the source tree at ./drivers/of and it's dated October 2026 — so like, future vibes, main character energy, we love to see it 🌟💖 go forth and match those nodes 🧚‍♀️
