The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.
Some DWC3 implementations such as Xilinx are hooked up coherently and need
to set the 'dma-coherent' property.
