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
