[PATCH] dt-bindings: usb: genesys,gl850g: allow downstream device subnodes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

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.
