+PXA LCD Controller
+------------------
+
+Required properties:
+ - compatible : one of these
+ "marvell,pxa2xx-lcdc",
+ "marvell,pxa270-lcdc",
+ "marvell,pxa300-lcdc"
+ - reg : should contain 1 register range (address and length).
+ - interrupts : framebuffer controller interrupt.
+ - clocks: phandle to input clocks
+
+Required nodes:
+ - port: connection to the LCD panel (see video-interfaces.txt)
+ This node must have its properties bus-width and remote-endpoint set.
+ If the panel is not a TFT color panel, then a "lcd-type" property in
+ the panel should specify the panel type.
+ This panel node should be in the board dts.
+
+Example:
+ lcd-controller@40500000 {
+ compatible = "marvell,pxa2xx-lcdc";
+ reg = <0x44000000 0x10000>;
+ interrupts = <17>;
+ clocks = <&clks CLK_LCD>;
+ status = "okay";
+
+ port {
+ lcdc_out: endpoint {
+ remote-endpoint = <&panel_in>;
+ bus-width = <16>;
+ };
+ };
+ };
