Add documentation for the devicetree bindings of the LCD controller present in
the JZ47xx family of SoCs from Ingenic.
Signed-off-by: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

Notes:
v2: Remove ingenic,panel property.
v3: - Rename compatible strings from ingenic,jz47XX-drm to ingenic,jz47XX-lcd
- The ingenic,lcd-mode property is now read from the panel node instead
of from the driver node
v4: Remove ingenic,lcd-mode property completely.

+Ingenic JZ47xx LCD driver
+
+Required properties:
+- compatible: one of:
+ * ingenic,jz4740-lcd
+ * ingenic,jz4725b-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@13050000 {
+ compatible = "ingenic,jz4725b-lcd";
+ reg = <0x13050000 0x1000>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <31>;
+
+ clocks = <&cgu JZ4725B_CLK_LCD>;
+ clock-names = "lcd";
+
+ port {
+ panel_output: endpoint {
+ remote-endpoint = <&panel_input>;
+ };
+ };
+};
