I started to look at the audio, and I can't find a use for an audio port in the OF graph. As far as I understand, we will be using the hdmi-codec, that still requires an ASoC card to create the link between our i2s controller and the HDMI controller. This work perfectly for us, but as far as I know, the simple-card stuff only requires a phandle, and not an OF graph endpoint, right? Thanks!
