Hi Mark, This patch and hence a full series of 13 patches is waiting for a long time now due to your missing ack on this DT binding patch. I have addressed your review comments given on earlier version - http://www.spinics.net/lists/devicetree/msg11550.html Please check this and give an ack if it is fine to be merged.
