I wasn't able to fix that.

If I change

 allOf:
-  - $ref: bridge/synopsys,dw-hdmi.yaml#
+  - $ref: synopsys,dw-hdmi.yaml#

then make dt_binding_check still reports:

Unknown file referenced: [Errno 2] No such file or directory: '/Users/hns/Library/Python/3.7/lib/python/site-packages/dtschema/schemas/bridge/synopsys,dw-hdmi.yaml'

BR and thanks,
