This driver is ported from NXP i.MX U-Boot version imx_v2019.04 and some changes have also been made to adapt to U-Boot.
Add the Cadence USB3 IP(CDNS3) driver for the gadget (device mode). The CDNS3 gadget driver support DM mode. CONFIG_DM_USB_GADGET
should
be enabled when use this driver. And gadget_is_cdns3 checking is added to provide bcdUSB value in device descriptor.
The cadence core isn't xhci compatible ? Sigh ...
Actually, I'm not very understand what the xhci compatible means? The cadence core can support usb peripheral and host. But for now, we just done the gadget part in the core code. If it needed later, we can add the host part to it.
So this is all needed to support gadget on the cadence3 ?
Yes, this patch is all needed for cdns3 usb gadget driver. I have already validated this on i.MX8 platform.
