Kernel-4.18.0-80.el8_tps65086

  • TPS65086 Power Management Integrated Circuit (PMIC) bindings

Required properties:

  • compatible : Should be “ti,tps65086”.
  • reg : I2C slave address.
  • interrupt-parent : Phandle to the parent interrupt controller.
  • interrupts : The interrupt line the device is connected to.
  • interrupt-controller : Marks the device node as an interrupt controller.
  • #interrupt-cells : The number of cells to describe an IRQ, should be 2.
             The first cell is the IRQ number.
             The second cell is the flags, encoded as trigger
             masks from ../interrupt-controller/interrupts.txt.
    
  • gpio-controller : Marks the device node as a GPIO Controller.
  • #gpio-cells : Should be two. The first cell is the pin number and
                         the second cell is used to specify flags.
                         See ../gpio/gpio.txt for more information.
    
  • regulators: : List of child nodes that specify the regulator
                         initialization data. Child nodes must be named
                         after their hardware counterparts: buck[1-6],
                         ldoa[1-3], swa1, swb[1-2], and vtt. Each child
                         node is defined using the standard binding for
                         regulators and the optional regulator properties
                         defined below.
    

Optional regulator properties:

  • ti,regulator-step-size-25mv : This is applicable for buck[1-6], set this
                 if the regulator is factory set with a 25mv
                 step voltage mapping.
    
  • ti,regulator-decay : This is applicable for buck[1-6], set this if
                 the output needs to decay, default is for
                 the output to slew down.
    

Example:

pmic: tps65086@5e {
    compatible = "ti,tps65086";
    reg = <0x5e>;
    interrupt-parent = <&gpio1>;
    interrupts = <28 IRQ_TYPE_LEVEL_LOW>;
    interrupt-controller;
    #interrupt-cells = <2>;
    gpio-controller;
    #gpio-cells = <2>;

    regulators {
        buck1 {
            regulator-name = "vcc1";
            regulator-min-microvolt = <1600000>;
            regulator-max-microvolt = <1600000>;
            regulator-boot-on;
            ti,regulator-decay;
            ti,regulator-step-size-25mv;
        };
    };
};
