+*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";
+ reg = <0x60>;
+
+ red-power {
+ label = "pca:red:power";
+ type = <PCA9532_TYPE_LED>;
+ };
+ green-power {
+ label = "pca:green:power";
+ type = <PCA9532_TYPE_LED>;
+ };
+ };
