This series adds preliminary support for USB 3.0 using the Dual Role Devices DRD based on DWC3 controller
One controller is in host mode :
1 Hub (5 Gb/s, 0mA) | U-Boot XHCI Host Controller | +-2 Mass Storage (480 Mb/s, 100mA) TDK LoR TF10 C900587416E2C552
The other is in gadget mode, and to test it out, I enabled rockusb
Currently it works to remotely reboot the board e.g. :
$ sudo rkdeveloptool ld DevNo=1 Vid=0x2207,Pid=0x350b,LocationID=601 Maskrom $ sudo rkdeveloptool rd Reset Device OK.
=> rockusb 0 mmc 0 dwc3-generic-peripheral usb@fc000000: request 00000000edf44580 was not queued to ep1in-bulk rockkusb set reboot flag: 0 resetting ...
For a typeC to typeC gadget connection, it only works in one orientation. To get orientation flipping support, another patch series is required, for the fairchild fusb driver and type C stack.
Current patch series also adds the USB-DP combo phy driver.
The DWC3 controllers each have two PHYs, one for USB 2.0 (the inno2 usb2 phy) and the usbdp for USB 3.0 .
