pch_udc_wri...e_interrupts(9)

💖 pch_udc_write_device_interrupts(9) 💖

okay bestie, so this one lives in the Kernel API Manual and it's literally the function that pokes the device interrupt register for the pch_udc driver. short king, but important. let's get into it ✨

---

✨ NAME ✨

pch_udc_write_device_interrupts — writes device interrupts 🫶

like, it writes them. that's the whole vibe. no cap.

---

🌸 SYNOPSIS 🌸

void pch_udc_write_device_interrupts (struct pch_udc_dev *dev , u32 val );

the way this signature just... sits there. returns void btw — it gives nothing back, king behavior honestly 👑

---

🎀 ARGUMENTS 🎀

• dev — a reference to a structure of type pch_udc_regs. yes bestie, pch_udc_regs, that's what the page says, we don't question it, we just pass the pointer 💅
• val — the value that gets written to the interrupt register. the actual payload. the moment. the main character of the write ✨

---

🦋 SEE ALSO 🦋

okay so this is the part where the page goes absolutely feral and lists basically the entire driver's extended family. buckle up, we're going through the whole group chat 💖

🧚 quick vibe check: this page covers exactly what's on it and nothing more — we're not out here inventing behavior, bestie. read the source if you want the lore.

and that's the tea 🍓 this little gem lives over in ./drivers/usb/gadget/udc and the page is dated October 2026. go forth and write those device interrupts, queen 👑💜
