1Silicon Image SiI9234 HDMI/MHL bridge bindings
2
3Required properties:
4	- compatible : "sil,sii9234".
5	- reg : I2C address for TPI interface, use 0x39
6	- avcc33-supply : MHL/USB Switch Supply Voltage (3.3V)
7	- iovcc18-supply : I/O Supply Voltage (1.8V)
8	- avcc12-supply : TMDS Analog Supply Voltage (1.2V)
9	- cvcc12-supply : Digital Core Supply Voltage (1.2V)
10	- interrupts: interrupt specifier of INT pin
11	- reset-gpios: gpio specifier of RESET pin (active low)
12	- video interfaces: Device node can contain two video interface port
13			    nodes for HDMI encoder and connector according to [1].
14			    - port@0 - MHL to HDMI
15			    - port@1 - MHL to connector
