pxa_udc_suspend(9)

🎀 NAME 🎀

Okay bestie, welcome to the Kernel API Manual page for pxa_udc_suspend(9)! The function is pxa_udc_suspend — Suspend udc device. That's the whole name, no cap. 💅

✨ SYNOPSIS ✨

Here's the signature exactly as it is, iconic spacing and all:

int pxa_udc_suspend (struct platform_device *_dev , pm_message_t state
);

🦋 ARGUMENTS 🦋

• _dev — platform device, typed struct platform_device *. It's the platform device, periodt.
• state — suspend state, typed pm_message_t.

💖 DESCRIPTION 💖

So what does it do? Suspends udc: it saves the configuration registers (UDCCR*), then it disables the udc device. That's the whole flow, bestie — save those regs, then disable the udc. ✨
