Right. And then there are the HDMI versions, and things like HDMI
Ethernet Channel. After looking at these a bit, I don't think the HDMI
connector needs any of those (hdmi version, eth) defined.

So...

	compatible = "hdmi-connector";
	type = "a";

Or

	compatible = "hdmi-connector";
	type-a;

I don't right away see any big pro with either one compared to the other.
