I really don't know what we should use here,
I just have a look at other SoC:
rk3328: "HDMI"
rk3399: "hdmi-sound"
r8a774c0-cat874: "CAT874 HDMI sound"
But maybe it's time to introduce proper name:
What about :
sun50i-a64-hdmi
sun50i-h6-hdmi
How should we handle this with h3 / h5 ?
settings the simple-audio-card,name in each SoC dts?
Or using sun50i-h3-hdmi as they are both identical?

Clement
