+Silicon Image SiI8620 HDMI/MHL bridge bindings
+
+Required properties:
+       - compatible: "sil,sii8620"
+       - reg: i2c address of the bridge
+       - cvcc10-supply: Digital Core Supply Voltage (1.0V)
+       - iovcc18-supply: I/O Supply Voltage (1.8V)
+       - interrupts, interrupt-parent: interrupt specifier of INT pin
+       - reset-gpios: gpio specifier of RESET pin
+       - clocks, clock-names: specification and name of "xtal" clock
+       - video interfaces: Device node can contain video interface port
+                           node for HDMI encoder according to [1].
