[PATCH v2 0/2] usb: spacemit: k3: Add USB2.0 support

[Yixun Lan]

There is one USB2.0 host in K3 SoC which actually use DWC3 IP but only 
provide USB2.0 functionality, and with only one USB2 PHY connected.

This series try to add USB2.0 support for SpacemiT K3 SoC, and will
enable it for Pico-ITX board in a separate patch. There is a run-time
dependency on USB phy[1], Hub[2] and reset[3] patches, but each series
should be quite independent, so I intend to not add prerequisite id
for the dependency here.

For people who interested, I've collected all patches and put a complete
branch here[4].
