+TI/National Semiconductor LP3943 MFD driver
+
+Required properties:
+  - compatible: "ti,lp3943"
+  - reg: I2C slave address. From 0x60 to 0x67.
+
+LP3943 consists of two sub-devices, lp3943-gpio and lp3943-pwm.
+
+For the LP3943 GPIO properties please refer to:
+Documentation/devicetree/bindings/gpio/gpio-lp3943.txt
+
+For the LP3943 PWM properties please refer to:
+Documentation/devicetree/bindings/pwm/pwm-lp3943.txt
+
+Example:
+
+lp3943@60 {
+	compatible = "ti,lp3943";
+	reg = <0x60>;
+
+	gpioex: gpio {
+		compatible = "ti,lp3943-gpio";
+		gpio-controller;
+		#gpio-cells = <2>;
+	};
+
+	pwm3943: pwm {
+		compatible = "ti,lp3943-pwm";
+		#pwm-cells = <2>;
+		ti,pwm0 = <8 9 10>;
+		ti,pwm1 = <15>;
+	};
+};
