Q1 If we use full graph style card, and if it would like to reuse current existing CPU/CODEC driver, then, I think CPU/CODEC driver should support graph style too. (Now, I'm checking v4l2 side existing graph style driver) I know it is based on its current implementation, but basically YES ? Q2 If Q1 was Yes, to keeping ABI compatibility, that CPU/CODEC driver should support both "phandle" and "graph" style ? -- 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
