I did have a patch in my L2C cleanup series to provide these properties, but it got discarded - even though we have existing platforms which provide these values. The reason for that was because requiring new properties causes a DT breakage - previous versions of the DT suddenly stop working because the values necessary to setup the L2C have been removed from the kernel, and the older DT files do not contain the neccessary values either. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. -- 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
