Subject: Re: [U-Boot] [PATCH 0/3] USB: Add cadence USB3 gadget driver and host driver

These patches introduce new Cadence USBSS driver to U-Boot.
The first patch is to add the Cadence USB3 IP(CDNS3) driver for the usb gadget, but the host mode is not supported now. The second patch introduce the xhci-imx8 usb host driver separately. The cdns3 usb gadget driver and xhci-imx8 host driver both use DM mode.
The current driver has been validated on i.MX8 platform.

Thanks for your patches! Taking into account that this series introduces a brand new driver, it would be really nice to also have proper device tree bindings in doc/device-tree-bindings (so I can at least quickly enable it for my board, test it and leave my T-b tags).
Currently there is also no linux upstream bindings for the new IP, so this will be dedicated for U-Boot. In future when Linux is ready, need to migrate to use Linux bindings.
To let you test the patchset, suggest Sherry to create a branch on github or somewhere.
Regards, Peng.
I created a branch on github, you can access it at https://github.com/sherrysun1/u-boot-imx.git. It includes some patches which I tested for cdns3 driver on imx8qm/qxp, maybe useful to you. By the way, I also add device tree bindings in doc/device-tree-bindings/usb/ at my branch in github, in case you need. Feel free to let me know if any problems.
Best regards Sherry sun
Thanks
