We can't add properties that aren't documented. Macros should not include structural syntax; the < > around the cell value is part of the macro the way you've written it, but shouldn't be. It'd be simpler to just write: nvidia,swgroup = <0x00000000 0x000779ff>; We should only extend the binding in a backwards-compatible fashion, so we can't require that DTs contain this value. At least, there should be a default value defined for when the property doesn't exist. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
