+The SiI9022A is an ultra low-power HDMI transmitter. It supports resolutions from +standard definition 480i/p and 576i/p all the way to high-definition 720p, 1080i, +and 1080p, the highest resolution supported by HDTVs today. It also supports all

+PC resolutions up to UXGA for netbooks
+Required properties: +- compatible: Should be "sil,sii9022a". +- reg: The I2C address of the device. +- interrupts: Interrupt number to the cpu.
+Required nodes:
+The sii9022 has one video ports. Its connection is modelled using the OF +graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+- Video port 0 for the HDMI output

Your unit address (0) and reg don't match.
sii9022_out: endpoint {remote-endpoint = <&hdmi_con>;};
This needs to have a port for the input for the connection to your display controller.
