2020-07-24usb: cdns3: drd: simplify *switch_gadet and *switch_hostPawel Laszczak
Patch split function cdns3_drd_switch_gadget and cdns3_drd_switch_host into: - cdns3_drd_host_on - cdns3_drd_host_off - cdns3_drd_gadget_on - cdns3_drd_gadgett_off These functions don't have any shared code so it's better to have smaller, faster and easier functions.

2019-08-29usb: cdns3: Add Cadence USB3 DRD DriverPawel Laszczak
This patch introduce new Cadence USBSS DRD driver to Linux kernel. The Cadence USBSS DRD Controller is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI)configurations. The current driver has been validated with FPGA platform. We have support for PCIe bus, which is used on FPGA prototyping. The host side of USBSS-DRD controller is compliant with XHCI specification, so it works with standard XHCI Linux driver.
