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. Thanks!
