+led-backlight bindings
+
+This binding is used to describe a basic backlight device made of LEDs.
+It can also be used to describe a backlight device controlled by the output of
+a LED driver.
+
+Required properties:
+  - compatible: "led-backlight"
+  - leds: a list of LEDs
+
+Optional properties:
+  - brightness-levels: Array of distinct brightness levels. The levels must be
+                       in the range accepted by the underlying LED devices.
+                       This is used to translate a backlight brightness level
+                       into a LED brightness level. If it is not provided, the
+                       identity mapping is used.
+
+  - default-brightness-level: The default brightness level.
+
+Example:
+
+	backlight {
+		compatible = "led-backlight";
+
+		leds = <&led1>, <&led2>;
+		brightness-levels = <0 4 8 16 32 64 128 255>;
+		default-brightness-level = <6>;
+	};

+Crane Merchandising System - EL15203000 LED driver
+--------------------------------------------------
+
+This LED Board (aka RED LEDs board) is widely used in
+coffee vending machines produced by Crane Merchandising Systems.
+The board manages 3 LEDs and supports predefined blinking patterns
+for specific leds.
+
+Vending area LED encoded with symbol 'V' (hex code 0x56).
+Doesn't have any hardware blinking pattern.
+
+Screen light tube LED which surrounds vending machine screen and
+encoded with symbol 'S' (hex code 0x53). Supports blinking breathing pattern.
+
+Water Pipe LED encoded with symbol 'P' (hex code 0x50) and
+actually consists of 5 LEDs that exposed by protocol like one LED.
+Supports next patterns:
+- cascade pattern
+- inversed cascade pattern
+- bounce pattern
+- inversed bounce pattern
+
+Required properties:
+- compatible : "crane,el15203000"
+- #address-cells : must be 1
+- #size-cells : must be 0
+
+Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
+apply. In particular, "reg" and "spi-max-frequency" properties must be given.
+
+Optional LED sub-node properties:
+- function:
+	see Documentation/devicetree/bindings/leds/common.txt
+- color:
+	see Documentation/devicetree/bindings/leds/common.txt
