This series adds clock, PHY, and XHCI driver support for the USB3 controller found in the Allwinner H6 SoC. Below is a log showing it functioning on the Orange Pi 3.
Cheers, Samuel

on my OrangePi3 I get this upon power up (with an usb3 flash drive as well as a SD card reader):

A second retry makes the usb@5200000 pass though.
May be related, but sometimes it can then boot off the usb device, but sometimes I get this:
=> setenv boot_targets usb0 => boot

And sometimes it get further but then fails shortly after:
=> setenv boot_targets usb0 => boot

I don't know what the issue could be. I am not familiar with XHCI internals, and it works reliably for me. I have tried both a USB3 flash drive and a bus-powered USB3-to-SATA cable:
