+*NXP - pca9532 PWM LED Driver
+
+The PCA9532 family is SMBus I/O expander optimized for dimming LEDs.
+The PWM support 256 steps.
+
+Required properties:
+	- compatible:
+		"nxp,pca9530"
+		"nxp,pca9531"
+		"nxp,pca9532"
+		"nxp,pca9533"
+	- reg -  I2C slave address
+
+Each led is represented as a sub-node of the nxp,pca9530.
+
+Optional sub-node properties:
+	- label: see Documentation/devicetree/bindings/leds/common.txt
+	- type: Output configuration, see dt-bindings/leds/leds-pca9532.h (default NONE)
+	- linux,default-trigger: see Documentation/devicetree/bindings/leds/common.txt

+Example:
+  #include <dt-bindings/leds/leds-pca9532.h>
+
+  leds: pca9530@60 {
+    compatible = "nxp,pca9530";

 The class also introduces the optional concept of an LED trigger. A trigger
 is a kernel based source of led events. Triggers can either be simple or
 complex. A simple trigger isn't configurable and is designed to slot into

 nand-disk and sharpsl-charge triggers. With led triggers disabled, the code
