These patches introduce new Cadence driver to U-Boot. The first patch is to add the Cadence USB3 IP(CDNS3) core and driver for the usb gadget. The second patch introduce the xhci-imx8 usb host driver separately. The third patch introduce the cdns3 phy driver which can be used for both cdns3 host driver and gadget driver. The cdns3 usb gadget/host/phy driver are all used DM mode.
The current driver has been validated on i.MX8 platform. If someone want to test it, please note that the additional dts nodes/ config macros/clock driver are also essential. You can also get my test patches at https://github.com/sherrysun1/u-boot-imx.git to start your test quickly. Changes in v5: - Delete some unnecessary code. - Fix some issues about lack of parentheses. - Add separate patch for core framework changes. - Add "reg-names" for usb nodes in DT and use it to get reg values. - Use "cdns,usb3-1.0.0" compatible instead "cdns,usb3". - Add DM_FLAG_OS_PREPARE flag to xhci-imx8 driver.
