Subject: [PATCH 8/8] dt-bindings: display: Convert ingenic,lcd.txt to YAML
Convert the ingenic,lcd.txt to a new ingenic,lcd.yaml file.
In the process, the new ingenic,jz4780-lcd compatible string has been
added.

-Ingenic JZ47xx LCD driver
-
-Required properties:
-- compatible: one of:
- * ingenic,jz4740-lcd
- * ingenic,jz4725b-lcd
- * ingenic,jz4770-lcd
-- reg: LCD registers location and length
-- clocks: LCD pixclock and device clock specifiers.
- The device clock is only required on the JZ4740.
-- clock-names: "lcd_pclk" and "lcd"
-- interrupts: Specifies the interrupt line the LCD controller is connected to.

-Example:
-
-panel {
- compatible = "sharp,ls020b1dd01d";
-
- backlight = <&backlight>;
- power-supply = <&vcc>;
-
- port {
- panel_input: endpoint {
- remote-endpoint = <&panel_output>;
- };
- };
-};

-lcd: lcd-controller@...50000 {
