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
[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
Example:
sii9234@39 {
compatible = "sil,sii9234";
reg = <0x39>;
avcc33-supply = <&vcc33mhl>;
iovcc18-supply = <&vcc18mhl>;
avcc12-supply = <&vsil12>;
cvcc12-supply = <&vsil12>;
reset-gpios = <&gpf3 4 GPIO_ACTIVE_LOW>;
interrupt-parent = <&gpf3>;
interrupts = <5 IRQ_TYPE_LEVEL_HIGH>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
mhl_to_hdmi: endpoint {
remote-endpoint = <&hdmi_to_mhl>;
};
};
port@1 {
reg = <1>;
mhl_to_connector: endpoint {
remote-endpoint = <&connector_to_mhl>;
};
};
};
};
