+Silicon Image SiI9234 HDMI/MHL bridge bindings
+
+Required properties:
+ - compatible : "sil,sii9234".
+ - reg : I2C address for TPI interface, use 0x39
+ - avcc33-supply : MHL/USB Switch Supply Voltage (3.3V)
+ - iovcc18-supply : I/O Supply Voltage (1.8V)
+ - avcc12-supply : TMDS Analog Supply Voltage (1.2V)
+ - cvcc12-supply : Digital Core Supply Voltage (1.2V)
+ - interrupts: interrupt specifier of INT pin
+ - reset-gpios: gpio specifier of RESET pin (active low)
+ - video interfaces: Device node can contain two video interface port
+ nodes for HDMI encoder and connector according to [1].
+ - port@0 - MHL to HDMI
+ - port@1 - MHL to connector
+
