Maybe this is how this has to be done, but I'll still ask:
Considering that the HDMI audio is basically inseparable part of the OMAP HDMI video, and if a board has HDMI video connector connected to the SoC's HDMI, then it has HDMI audio.
So all of the above .dts changes are already implied when we have HDMI video on the board. Is there no way to prevent every board needing to add those exact same nodes to get HDMI audio?
