As this binding describes USB hubs, it's natural for them to have downstream devices. Change "additionalProperties" to "unevaluatedProperties" to allow properties defined in usb-device.yaml (for DT cells properties) and add a pattern-based downstream device subnode rule to match those subnodes. These changes allow downstream devices get defined under the hub. Signed-off-by: Icenowy Zheng <uwu@xxxxxxxxxx> --- This patch is sent to fix the problems shown for the patchset at [1], which declares a MAC-address-less ethernet adapter subnode of the GL850G to have its MAC address set from the bootloader.
