pch_udc_vbus_session(9)

💖 NAME 💖

okay bestie, this is pch_udc_vbus_session(9) from the Kernel API Manual — and it’s literally here to set or clearr the disconnect status. not me pointing out the clearr spelling, but that’s the original and we’re respecting the lore 😭💅

✨ SYNOPSIS ✨

signature drop, no edits, no vibes-based rewriting:

void pch_udc_vbus_session (struct pch_udc_dev *dev , int is_active );

🫶 ARGUMENTS 🫶

• dev — Reference to pch_udc_regs structure. 💖
• is_active — Parameter specifying the action: 0: indicating VBUS power is ending; !0: indicating VBUS power is starting. ⚡
