Subject: [PATCH 0/7] arm64: allwinner: a523: add USB3.0 support

From: Mikhail Kalashnikov <iuncuim@...il.com>

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
