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>; }; };
