💖 iudma_init_channel(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for iudma_init_channel(9) — we're talking about the one-time IUDMA channel initialization, and yes it's giving tiny-but-important setup moment ✨💅

✨ NAME ✨

iudma_init_channel — one-time IUDMA channel initialization. That's the whole vibe: it's the one-time init for an IUDMA channel, no cap 🫶

🌸 SYNOPSIS 🌸

the signature is right here, character for character:

int iudma_init_channel (struct bcm63xx_udc *udc , unsigned int ch_idx );

🎀 ARGUMENTS 🎀

• udc — a reference to the device controller. That's your controller reference, bestie 💖
• ch_idx — the channel to initialize. This tells the function which channel gets the one-time setup treatment ✨
