pch_udc_pcd_pullup(9)

🌸 NAME 🌸

pch_udc_pcd_pullup(9) — okay so bestie, this API is literally invoked to make the device visible/invisible to the host. That's the assignment, no cap. 💅

✨ SYNOPSIS ✨

int pch_udc_pcd_pullup (struct usb_gadget *gadget , int is_on );

Signature check: returns an int, takes a struct usb_gadget *gadget, and an int is_on, periodt. 🎀

🎀 ARGUMENTS 🎀

• gadget — Reference to the gadget driver. Like, the gadget driver's reference, main character energy only. 🫶
• is_on — Specifies whether the pull up is made active or inactive. So it's the on/off tea for the pull-up vibe. ✨

💖 DESCRIPTION 💖

Return codes, bestie — memorize these like your fave lyrics:

• 0 — Success 🎉
• -EINVAL — If the gadget passed is NULL 😭 (so do not hand it a null gadget and expect a slay)
