Kernel-4.18.0-80.el8_lp3943

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>;
};

};
