Lontium LT8912 MIPI-DSI to LVDS and HDMI/MHL bridge bindings
Required properties and nodes:
- compatible: "lontium,lt8912"
- hpd-gpios: a GPIO spec for the hot-plug detect pin
- port: node referencing the MIPI-DSI source
- reg: i2c address of the bridge
- i2c-bus: phandle of an I2C controller used for register access
One of:
- ddc-i2c-bus: reference to a DDC-I2C bus for EDID retrival
- display-timings: hardcoded display timings if ddc-i2c-bus does not exist.
Refer to binding doc display-timing.txt for details
Optional properties:
- reset-gpios: a GPIO spec for the reset pin
Examples:
&i2c1 {
lt8912@48 {
compatible = "lontium,lt8912";
ddc-i2c-bus = <&i2c0>;
hpd-gpios = <&gpio1 31 GPIO_ACTIVE_HIGH>;
reg = <0x48>;
port {
lt8912_1_in: endpoint {
remote-endpoint = <&mipi_dsi_bridge1_out>;
};
};
&i2c2 {
lt8912@48 {
compatible = "lontium,lt8912";
hpd-gpios = <&gpio1 31 GPIO_ACTIVE_HIGH>;
reg = <0x48>;
port {
lt8912_1_in: endpoint {
remote-endpoint = <&mipi_dsi_bridge1_out>;
};
};
display-timings {
native-mode = <&timing0>;
timing0: timing0 {
clock-frequency = <74250000>;
hactive = <1280>;
vactive = <720>;
hfront-porch = <110>;
hsync-len = <40>;
hback-porch = <220>;
vfront-porch = <5>;
vsync-len = <5>;
