Add the Marvell Dove LCD controller DT binding documentation. The
clock names used here are intentionally taken from the specification
for the Dove SoC.

+Device Tree bindings for Armada DRM CRTC driver
+
+Required properties:
+ - compatible: value should be "marvell,dove-lcd".
+ - reg: base address and size of the LCD controller
+ - interrupts: single interrupt number for the LCD controller
+ - port: video output port with endpoints, as described by graph.txt
+
+Optional properties:
+
+ - clocks: as described by clock-bindings.txt
+ - clock-names: as described by clock-bindings.txt
+ "axiclk" - axi bus clock for pixel clock
+ "plldivider" - pll divider clock for pixel clock
+ "ext_ref_clk0" - external clock 0 for pixel clock
+ "ext_ref_clk1" - external clock 1 for pixel clock
+
+Note: all clocks are optional but at least one must be specified.
+Further clocks may be added in the future according to requirements of
+different SoCs.
+
+Example:
+
+ lcd0: lcd-controller at 820000 {
+ compatible = "marvell,dove-lcd";
+ reg = <0x820000 0x1000>;
+ interrupts = <47>;
+ clocks = <&si5351 0>;
+ clock-names = "ext_ref_clk_1";
+ };
