Lontium LT8912 MIPI-DSI to LVDS and HDMI/MHL bridge bindings

Required properties:
 - compatible: "lontium,lt8912"
 - reg: virtual channel id
 - reset-gpios: a GPIO spec for the reset pin
 - i2c-bus: phandle of an I2C controller used for register access
 - display-timings : Refer to binding doc display-timing.txt for details
 - digi,dsi-lanes: number of DSI lanes used by the bridge, a whole number
                   between 1 and 4 (both inclusive)
 - no-hpd: disable hot-plug detection, assumes display always connected
 - no-edid: do not use EDID modes, use the display-timings provided in the dt

Optional properties:
 - vdd1-supply: Power supply for the lt8912 chip
 - vdd2-supply: Power supply for the lt8912 chip

Example:

&dsi {
	status = "okay";

	lt8912@0 {
		compatible = "lontium,lt8912";
		reg = <0>;
		reset-gpios = <&gpio0 RK_PA2 GPIO_ACTIVE_LOW>;
		i2c-bus = <&i2c1>;

		display-timings {
			native-mode = <&timing0>;

			timing0: timing0 {
