-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
