fwnode_grap...dpoint_count(9)

💅 fwnode_graph_get_endpoint_count(9)

okay bestie, so this little cutie lives in the Kernel API Manual and her whole entire job is counting endpoints on a device node. it's giving "headcount at the function but make it ✨firmware✨". let's get into it 🎀

---

🌸 NAME 🌸

fwnode_graph_get_endpoint_count — count endpoints on a device node, that's it, that's the gig 💖

---

✨ SYNOPSIS ✨

unsigned int fwnode_graph_get_endpoint_count (const struct fwnode_handle
*fwnode , unsigned long flags );

like, you hand her a fwnode and some flags, and she gives you back an unsigned int. main character returns only 🔥

---

🦋 ARGUMENTS 🦋

• fwnode — the node related to a device. literally just the node you're curious about, no cap 🫶
• flags — fwnode lookup flags. and yeah, she counts endpoints in a device node — that's the vibe check right there 💅

---

🧚 DESCRIPTION 🧚

so here's the tea ☕: if the FWNODE_GRAPH_DEVICE_DISABLED flag is specified, then she also counts the unconnected endpoints and the endpoints connected to disabled devices. lowkey generous of her ngl 😭💜

fr fr, that's the only extra behaviour — no other flags doing secret side quests, iykyk.
