[PATCH 1/2] dt-bindings: usb: aspeed,usb-vhub: Add ast2700 support

From: Ryan Chen

Date: Wed Nov 26 2025 - 03:27:14 EST


Add the "aspeed,ast2700-usb-vhub" compatible. The ast2700 vhub
controller requires an reset, so make the "resets" property
mandatory for this compatible to reflect the hardware requirement.
