+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>;
+       };
