I don't think this is going to work. The omap-abe-twl6040 machine driver only handles mcpdm and dmic right know. 'ti,audio-codec' is not even supported and it is kind of misleading naming in this context since twl6040 is also a codec, so why only the dummy-hdmi codec deserves to be called as codec. Furthermore: we have the omap-hdmi-card machine driver to handle the HDMI audio. It lacks DT support AFAIK but should not be a big deal to add the bindings. To get the hdmi audio working you also need to have phandle for the omap-hdmi DAI, the codec alone is not enough.
