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.
