dwc2_backup_...al_registers(9)

💖 NAME 💖

Okay so bestie, welcome to the Kernel API Manual page for dwc2_backup_global_registers — and yes, it's exactly that girl: she backs up the global controller registers. The reason? When you're suspending the USB bus, those registers need to be backed up if controller power is disabled once suspended. No cap, that's the whole assignment. ✨

🦋 SYNOPSIS 🦋

int dwc2_backup_global_registers (struct dwc2_hsotg *hsotg );

🎀 ARGUMENTS 🎀

• hsotg — the programming view of the DWC_otg controller. That's the one and only parameter, bestie. 👑
