    1 TI/National Semiconductor LP3943 MFD driver
    2 
    3 Required properties:
    4   - compatible: "ti,lp3943"
    5   - reg: I2C slave address. From 0x60 to 0x67.
    6 
    7 LP3943 consists of two sub-devices, lp3943-gpio and lp3943-pwm.
    8 
    9 For the LP3943 GPIO properties please refer to:
   10 Documentation/devicetree/bindings/gpio/gpio-lp3943.txt
   11 
   12 For the LP3943 PWM properties please refer to:
   13 Documentation/devicetree/bindings/pwm/pwm-lp3943.txt
   14 
   15 Example:
   16 
   17 lp3943@60 {
   18         compatible = "ti,lp3943";
   19         reg = <0x60>;
   20 
   21         gpioex: gpio {
   22                 compatible = "ti,lp3943-gpio";
   23                 gpio-controller;
   24                 #gpio-cells = <2>;
   25         };
   26 
   27         pwm3943: pwm {
   28                 compatible = "ti,lp3943-pwm";
   29                 #pwm-cells = <2>;
   30                 ti,pwm0 = <8 9 10>;
   31                 ti,pwm1 = <15>;
   32         };
   33 };
