DT binding allows it:
HDMI Connector
==============
Required properties:
- compatible: "hdmi-connector"
- type: the HDMI connector type: "a", "b", "c", "d" or "e"
but DW HDMI bridge driver hardcodes it to type A. Actually, kernel has defines
only for type A and B.
Actually, many HDMI drivers have type A hardcoded...
