This series is a draft and does not include patches for dt-bindings.
The first series is necessary for testing on other devices and
initiating discussion.
This series of patches adds USB 3.0 functionality for the
A523/A527/H728/T527 processor.Most of the code is derived from the BSP,
as the datasheet does not fully describe this feature.
I have verified functionality on two of my boards, walnutpi 2b (t527)
and x96qproplus (h728). When testing usb3.0 on x96qproplus, I get
reconnections of my nvme, it looks like the port does not provide enough
current to work. I have encountered similar complaints from users of the
device on Android. In the case of walnutpi, there is no such problem.
Based on 6.17-rc1
