+led-backlight bindings
+
+Required properties:
+ - compatible: "led-backlight"
+ - leds: phandle to a led OF node [0]
+ - brightness-levels: Array of distinct LED brightness levels. These
+ are in the range from 0 to 255, passed to the LED class driver.
+ - default-brightness-level: the default brightness level (index into the
+ array defined by the "brightness-levels" property)
+
+Optional properties:
+ - power-supply: regulator for supply voltage
+ - enable-gpios: contains a single GPIO specifier for the GPIO which enables
+ and disables the backlight (see GPIO binding[1])
+

+
+Example:
+
+ backlight {
+ compatible = "led-backlight";
+ leds = <&backlight_led>;
+
+ brightness-levels = <0 4 8 16 32 64 128 255>;
+ default-brightness-level = <6>;
+
+ power-supply = <&vdd_bl_reg>;
+ enable-gpios = <&gpio 58 0>;
+ };
