Or, just use numbers in the docs, and macros in the dtsi files. If you prefer the latter, just let me know and I'll fixup the other patch when applying these. Otherwise, you can just send a v5 of the two patches affected. thx, Jason. -- 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
