Yes, the DT binding is incorrect. I will refer to 
broadcom-bluetooth.yaml to make the modifications as follows:

properties:
   compatible:
     oneOf:
       - items:
           - enum:
               - amlogic,w265s1-bt
               - amlogic,w265p1-bt
           - const: amlogic,w155s2-bt
       - enum:
           - amlogic,w155s2-bt
           - amlogic,w265s2-bt

Please let me know if these changes are acceptable or if there are any 
further adjustments needed.
