+PXA LCDC Framebuffer
+--------------------
+
+Required properties:
+ - compatible :
+       "marvell,pxa2xx-lcdc",
+ - reg : Should contain 1 register ranges(address and length).
+        Can contain an additional register range(address and length)
+        for fixed framebuffer memory. Useful for dedicated memories.
+ - interrupts : framebuffer controller interrupt
+
+Required nodes:
+ - clocks: phandle to input clocks.
+ - port: connection to the LCD panel (see video-interfaces.txt)
+        This nodes must have its properties bus-width and remote-endpoint set.
+        This should be in the board dts.
+
+Example:
+
+       lcd-controller@40500000 {
+               compatible = "marvell,pxa2xx-lcdc";
+               reg = <0x44000000 0x10000>;
+               interrupts = <17>;
+               clocks = <&clks CLK_LCD>;
+               interrupts = <23>;

+               status = "okay";
+
+               port {
+                       lcdc_out: endpoint {
+                               remote-endpoint = <&panel_in>;
+                               bus-width = <16>;
+                       };
+               };
+       };
+
+PXA LCDC Display
+----------------
+Required properties (as per of_videomode_helper):
+ - lcd-type: either "mono-stn", "mono-dstn", "color-stn", "color-dstn",
+                   "color-tft", "smart-panel"
