[PATCH 0/3] add dwc2 support for px30

[PATCH 0/3] add dwc2 support for px30

[Heiko Stuebner]

This is split out from the series adding the px30 support, due to
the dwc2 binding change not having landed yet in a maintainer tree.

The Acked binding change should go through some usb tree, while
I'll pick up the dts changes once that has happened.

The binding itself is unchanged.

Do you want to pick that patch through one of the usb trees, or should
I just apply it with the arm64 devicetree-patches?


Thanks
Heiko
