✨ NAME ✨

okay bestie, welcome to the pxa_udc_probe(9) page in the Kernel API Manual — this one is short, sweet, and literally all about probing the udc device 👑💖.

pxa_udc_probe — probes the udc device. periodt 💅

---

🦋 SYNOPSIS 🦋

the signature is literally this, no cap:

int pxa_udc_probe (struct platform_device *pdev );

---

💅 ARGUMENTS 💅

• pdev — platform device. that's the whole argument, bestie 🫶

🌸 DESCRIPTION 🌸

okay so it does the basic init era: allocates udc clock, creates sysfs files, requests irq. that's the whole description and it's giving setup realness ✨
