💾 dwc2_backup_host_registers(9) 💾

okay so bestie, this page is from the Kernel API Manual, and it's all about giving the controller's host registers a little backup moment. ✨

🎀 NAME 🎀

dwc2_backup_host_registers — backup controller host registers. When the USB bus is being suspended, the registers need to be backed up if controller power is disabled once suspended. That's the assignment, no cap. 💅

🌸 SYNOPSIS 🌸

int dwc2_backup_host_registers (struct dwc2_hsotg *hsotg );

🦋 ARGUMENTS 🦋

• hsotg — the programming view of the DWC_otg controller. That's the whole vibe check for this one. 🫶
