pxa_ep_setup(9)

💫 pxa_ep_setup(9) — the "go find your endpoint and set up its UDCCR" girlie 💫

okay so bestie, welcome to the Kernel API Manual entry for pxa_ep_setup, and honestly? she's short, she's sweet, she does exactly one (1) thing. lowkey iconic behavior. 🎀

---

✨ NAME ✨

pxa_ep_setup — sets up a usb physical endpoint 🦋

---

🌸 SYNOPSIS 🌸

void pxa_ep_setup (struct pxa_ep *ep );

like, that's it. that's the whole signature. no sneaky extra args, no surprises. periodt. 💅

---

💖 ARGUMENTS 💖

• ep — the pxa27x physical endpoint, aka the main character of this whole function. she's a struct pxa_ep * and she's literally the only thing you pass in. 🫶

---

🔥 DESCRIPTION 🔥

so what does she do? fr fr, it's simple:

Find the physical pxa27x ep, and setup its UDCCR ✨

that's the vibe. locate that endpoint, then get its UDCCR all sorted. no cap, no extra steps, no secret side quests — that's the whole description and we're not gonna pretend otherwise. 😭
