bcm63xx_ep_init(9)

💖 bcm63xx_ep_init — the Kernel API Manual era ✨

okay so bestie, welcome to the bcm63xx_ep_init(9) page, the most niche little corner of the Kernel API Manual and honestly? we're gonna slay it together 💅

🎀 NAME 🎀

bcm63xx_ep_init — the Initial (one-time) endpoint initialization girlie. that's it. that's the whole vibe. one time only, no reruns 🫶

---

✨ SYNOPSIS ✨

void bcm63xx_ep_init (struct bcm63xx_udc *udc );

like, she takes exactly one thing and she returns void — no little gift back, no nothing. main character energy fr fr 💀

🌸 ARGUMENTS 🌸

• udc — a Reference to the device controller, aka your whole entire device controller situation. hand her this and she's set 💖

ngl the whole thing is one-time initialization, so don't be out here calling it on loop like it's a TikTok sound. once. that's the assignment ✨

lowkey a reminder that this page literally only gives you the one-time endpoint init, the rest of the lore lives in all those refs above. iykyk 🧚

and that's the page, bestie!! this little gem lives in ./drivers/usb/gadget/udc, dated October 2026, and it's brought to you by the Kernel API Manual because of course it is 💜 mwah, go init exactly one endpoint and text me after 🍓💅
