[PATCH 0/4] rockchip: rk3588: add USB 3.0 support

[Eugen Hristev <eugen.hristev@collabora.com>]

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.

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 .
