bcm63xx_uninit_udc_hw(9)

okay bestie, you're looking at bcm63xx_uninit_udc_hw(9) from the Kernel API Manual, and it's literally the “pack up the hardware before the driver leaves the group chat” function. 💅✨

✨ NAME ✨

bcm63xx_uninit_udc_hw — shut down the hardware prior to driver removal. No cap, that's the whole vibe: hardware cleanup era before the driver gets removed. 🫶

🌸 SYNOPSIS 🌸

void bcm63xx_uninit_udc_hw (struct bcm63xx_udc *udc );

🎀 ARGUMENTS 🎀

• udc — a reference to the device controller. That's the controller bestie you're shutting down, iykyk. 🦋

💖 DESCRIPTION 💖

This one just masks the IUDMA IRQs and releases the clocks. Simple, iconic, lowkey essential. ✨

heads up bestie: it is assumed that bcm63xx_udc_stop has already run, and the clocks are stopped. So don't come in here expecting it to do that part too — that is not the assignment. 😭
