  • Dialog DA9062 Power Management Integrated Circuit (PMIC)

Product information for the DA9062 and DA9061 devices can be found here:

The DA9062 PMIC consists of:

Device Supply Names Description

da9062-regulator : : LDOs & BUCKs
da9062-rtc : : Real-Time Clock
da9062-onkey : : On Key
da9062-watchdog : : Watchdog Timer
da9062-thermal : : Thermal

The DA9061 PMIC consists of:

Device Supply Names Description

da9062-regulator : : LDOs & BUCKs
da9062-onkey : : On Key
da9062-watchdog : : Watchdog Timer
da9062-thermal : : Thermal

Required properties:

  • compatible : Should be
    “dlg,da9062” for DA9062
    “dlg,da9061” for DA9061
  • reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
    modified to match the chip’s OTP settings).
  • interrupt-parent : Specifies the reference to the interrupt controller for
    the DA9062 or DA9061.
  • interrupts : IRQ line information.
  • interrupt-controller

See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
further information on IRQ bindings.

Sub-nodes:

  • regulators : This node defines the settings for the LDOs and BUCKs.
    The DA9062 regulators are bound using their names listed below:

    buck1 : BUCK_1
    buck2 : BUCK_2
    buck3 : BUCK_3
    buck4 : BUCK_4
    ldo1 : LDO_1
    ldo2 : LDO_2
    ldo3 : LDO_3
    ldo4 : LDO_4

    The DA9061 regulators are bound using their names listed below:

    buck1 : BUCK_1
    buck2 : BUCK_2
    buck3 : BUCK_3
    ldo1 : LDO_1
    ldo2 : LDO_2
    ldo3 : LDO_3
    ldo4 : LDO_4

    The component follows the standard regulator framework and the bindings
    details of individual regulator device can be found in:
    Documentation/devicetree/bindings/regulator/regulator.txt

  • rtc : This node defines settings required for the Real-Time Clock associated
    with the DA9062. There are currently no entries in this binding, however
    compatible = “dlg,da9062-rtc” should be added if a node is created.

  • onkey : See ../input/da9062-onkey.txt

  • watchdog: See ../watchdog/da9062-watchdog.txt

  • thermal : See ../thermal/da9062-thermal.txt

Example:

pmic0: da9062@58 {
    compatible = "dlg,da9062";
    reg = <0x58>;
    interrupt-parent = <&gpio6>;
    interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
    interrupt-controller;

    rtc {
        compatible = "dlg,da9062-rtc";
    };

    regulators {
        DA9062_BUCK1: buck1 {
            regulator-name = "BUCK1";
            regulator-min-microvolt = <300000>;
            regulator-max-microvolt = <1570000>;
            regulator-min-microamp = <500000>;
            regulator-max-microamp = <2000000>;
            regulator-boot-on;
        };
        DA9062_LDO1: ldo1 {
            regulator-name = "LDO_1";
            regulator-min-microvolt = <900000>;
            regulator-max-microvolt = <3600000>;
            regulator-boot-on;
        };
    };
};
