[PATCH 0/4] Add CIX Sky1 Cadence USB3 support

[Peter Chen]

This series adds library support for cdns3 platform driver as well as the
first user CIX Sky1 USB3. It is the follow-up of Arnd's suggestion [1] for
helping cdns3 module dependencies and new developers working on it.
The final two patches document the Sky1 binding and describe the USB4/USB5
controller instances in the Sky1 device tree and enable them on the Radxa
Orion O6 board.
