I suppose if you wanted to have 64 possible combinations of some attribute you would just extend it to two 32 bit numbers in sequence? I don't see the limitation here, and hopefully there isn't a limitation so that we can specify sufficiently large numbers with more bits if we need to. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
