✨ NAME ✨

dwc3_phy_setup — Configure USB PHY Interface of DWC3 Core 🌸

🦋 SYNOPSIS 🦋

int dwc3_phy_setup (struct dwc3 *dwc );

🎀 ARGUMENTS 🎀

• dwc — Pointer to our controller context structure 💖 literally our controller context struct, hold her gently

💅 DESCRIPTION 💅

so what does she actually do?? she returns 0 on success, periodt. 👑

here's the tea though: the USB PHY interfaces get configured but not initialized — nope, not yet, she's not doing all that 🙈 it's giving "hair done, makeup not started" energy.

the PHY interfaces and the PHYs themselves get initialized together with the core over in dwc3_core_init. so like, they're a package deal, iykyk 💜 the way that they literally cannot be separated, we love a codependent queen 😭

🌈 SEE ALSO 🌈

Kernel file ./drivers/usb/dwc3/core.c — go read her, she's iconic 👑
