💅 dwc2_handle_otg_intr(9)

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, no I'm not making it up — and today's main character is dwc2_handle_otg_intr, literally the function that catches OTG interrupts for you so you don't have to 🎀

---

✨ NAME ✨

dwc2_handle_otg_intr — she handles the OTG Interrupts 💖 fr fr. Like, she reads the OTG Interrupt Register (GOTGINT) to figure out which interrupt actually happened. That's the whole job. She reads the register, she determines the interrupt, she slays 👑

---

🌸 SYNOPSIS 🌸

void dwc2_handle_otg_intr (struct dwc2_hsotg *hsotg );

that's it. that's the signature. gorgeous, no notes 🫶

---

🦋 ARGUMENTS 🦋

• hsotg — the programming view of the DWC_otg controller. yes "programming view", that's the actual phrase, she's giving very much main character energy — it's the handle you hand her so she knows which controller she's working with 💜
