Hi Rob, Thanks for the quick reply. I can make change in machine driver so that - The presence of rockchip,audio-codec enable max98090 - The presence of rockchip,hdmi-codec enable HDMI. With that, we don't need the three properties added in this patch: "rockchip,rockchip-audio-max98090" for max98090-only. "rockchip,rockchip-audio-hdmi" for HDMI-only "rockchip,rockchip-audio-max98090-hdmi" for max98090 plus HDMI. I will post an update soon.
