-pwm-backlight bindings
-
-Required properties:
-  - compatible: "pwm-backlight"
-  - pwms: OF device-tree PWM specification (see PWM binding[0])
-  - brightness-levels: Array of distinct brightness levels. Typically these
-      are in the range from 0 to 255, but any range starting at 0 will do.
-      The actual brightness level (PWM duty cycle) will be interpolated
-      from these values. 0 means a 0% duty cycle (darkest/off), while the
-      last value in the array represents a 100% duty cycle (brightest).
-  - default-brightness-level: the default brightness level (index into the
-      array defined by the "brightness-levels" property)
-
-Optional properties:
-  - pwm-names: a list of names for the PWM devices specified in the
-               "pwms" property (see PWM binding[0])

-Example:
-
-        backlight {
-                compatible = "pwm-backlight";
-                pwms = <&pwm 0 5000000>;
-
-                brightness-levels = <0 4 8 16 32 64 128 255>;
-                default-brightness-level = <6>;
-        };
