The binding is saying that the compatible "should" be "fsl,t1040-qe-si" regardless of whether it's actually a t1040. Instead say that compatible must include "fsl,<chip>-qe-si" and give t1040 as an example. If you intend "fsl,t1040-qe-si" to be something that other compatible chips list, in addition to their own <chip> compatibles, then also say that explicitly. -Scott -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
