[PATCH v1 0/4] Add Google Tensor SoC USB support
From: Roy Luo
Date: Mon Oct 06 2025 - 19:21:46 EST
This series introduces support for the USB controller and PHY found on
Google Tensor SoCs (G5 and newer). This includes:
1. DWC3 Glue Driver: A new glue layer for the Synopsys DesignWare USB 3.0
controller (DWC3) as integrated into Google Tensor SoCs, including
hibernation support.
2. DWC3 DT Bindings: Device Tree binding documentation for the Google
Tensor SoC DWC3 controller.
3. USB PHY Driver: A new driver for the Google Tensor SoC USB PHY,
initially supporting high-speed operations.
4. USB PHY DT Bindings: Device Tree binding documentation for the Google
Tensor SoC USB PHY.
