Sometimes, when the USB controller experiences a timeout for the stop EP endpoint command for a timeout for processing commands, xhci driver will shutdown the USB controller. If you want to reactivate the USB controller, you need to follow the reactivation operation process. note: This patch is only applicable to the Phytium platform.

When a transmission error occurs, EP_CTX_STATE is not equal to EP_STATE_HALTED, and the reset endpoint command is forcibly sent for the specified PHYTIUM platform.

This patch provides support for Phytium usb tcm device driver, which can be used for communication with the PHYTIUM USB TCM.

During controller reactivation, if the xhci_generic_plat_probe function fails for any reason, attempting a shutdown operation at this stage will cause the shutdown function to use already released resources, which will trigger the system panic. Therefore, when the xhci_generic_plat_probe function fails, the shutdown function must be set to NULL.
