+ - reg: base address and size of memory-mapped region
+ - clocks: phandles to the clocks feeding the HDMI encoder
+ * ahb: the HDMI interface clock
+ * mod: the HDMI module clock
+ * pll-0: the first video PLL
+ * pll-1: the second video PLL
+ - clock-names: the clock names mentioned above
+
+ - ports: A ports node with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The
+ first port should be the input endpoint.
