pch_udc_init(9)

🦋 pch_udc_init(9) — the Kernel API Manual, bestie edition 💅

okay so this is a page from the Kernel API Manual, and it's about pch_udc_init ✨ lowkey one of those functions that just does the thing so everything else can vibe. Let's get into it.

🌸 NAME 🌸

pch_udc_init — this API initializes the usb device controller 🫶

💖 SYNOPSIS 💖

void pch_udc_init (struct pch_udc_dev *dev );

no cap, that's the whole signature. she takes one pointer and returns nothing (void, queen of not giving anything back 😌).

🎀 ARGUMENTS 🎀

• dev — a reference to the pch_udc_regs structure. that's the one you hand over so she knows which controller she's initializing, iykyk 💫

like… that's the whole friend group 😭 every one of them living in ./drivers/usb/gadget/udc, iconic behavior honestly 👑

ngl bestie, if you're here you probably want to read the whole cluster, not just this one — she's the entry point, not the whole story 🧚

and that's the page!! 🌈 this cutie came to you from the source/version path ./drivers/usb/gadget/udc and it's dated October 2026 — periodt, see you in the next one 💜🎀💫
