Hi Sylwester, again > It seems the graph based binding could cover above both cases. Apologies > if this has been explained before, but what are main reasons for introducing > the graph based binding? The big reason why I want to introduce OF-graph simple card is that I need to support HDMI sound. HDMI video side is already using OF-graph base DT binding. So it is useful if HDMI sound side can follow same style.
