✨ of_graph_ge...oint_by_regs(9) ✨

okay so bestie, like, real talk: this is a page from the Kernel API Manual (yes, the Linux kernel, we're literally in the big leagues 💅) and the function name is genuinely that long, don't @ me, that's just how it's spelled — of_graph_ge...oint_by_regs(9), ellipsis and all. iykyk 🎀

🌸 NAME 🌸

of_graph_get_endpoint_by_regs — bestie. it gets you an endpoint node that has specific identifiers. that's the whole vibe. ✨

🦋 SYNOPSIS 🦋

struct device_node * of_graph_get_endpoint_by_regs (const struct
       device_node *parent , int port_reg , int reg );

like, look at her. three args, one pointer out. iconic. 👑

💖 ARGUMENTS 💖

  • parent — pointer to the parent device node 🫶 (yes, the actual parent, we're going in)
  • port_reg — the identifier of the parent port node, and by "identifier" we mean the value of its reg property, periodt.
  • reg — the identifier of the endpoint node, again: value of the reg property. that one. 💅

⭐ RETURN ⭐

You get back an 'endpoint' node pointer — and she's a very specific girlie: she's the one identified by reg, and at the same time she's the child of a port node identified by port_reg. two whole criteria. main character energy fr fr. 🌈

🚨 bestie listen — reg and port_reg are ignored when they are -1. like, straight up not read. so if you pass -1 don't be out here expecting it to filter anything, okay?
🫶 and please, PLEASE — use of_node_put on the pointer when done. that's not optional, that's a reference you're holding. clean up after yourself, we don't leak. 😭

like. the whole squad. ate and left no crumbs 🍓🔥

and that's the tea, bestie 🎀 this masterpiece lives over in ./drivers/of and it's dated October 2026 — so yeah, of_graph_ge...oint_by_regs(9), Kernel API Manual, October 2026, ./drivers/of. mwah. go call of_node_put. 💋✨
