* Dialog DA9063 Power Management Integrated Circuit (PMIC)



DA9093 consists of a large and varied group of sub-devices (I2C Only):



Device                   Supply Names    Description

------                   ------------    -----------

da9063-regulator        :               : LDOs & BUCKs

da9063-rtc              :               : Real-Time Clock

da9063-watchdog         :               : Watchdog



======



Required properties:



- compatible : Should be "dlg,da9063"

- 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 DA9063.

- interrupts : IRQ line information.

- interrupt-controller



Sub-nodes:



- regulators : This node defines the settings for the LDOs and BUCKs. The

  DA9063 regulators are bound using their names listed below:



    bcore1    : BUCK CORE1

    bcore2    : BUCK CORE2

    bpro      : BUCK PRO

    bmem      : BUCK MEM

    bio       : BUCK IO

    bperi     : BUCK PERI

    ldo1      : LDO_1

    ldo2      : LDO_2

    ldo3      : LDO_3

    ldo4      : LDO_4

    ldo5      : LDO_5

    ldo6      : LDO_6

    ldo7      : LDO_7

    ldo8      : LDO_8

    ldo9      : LDO_9

    ldo10     : LDO_10

    ldo11     : LDO_11



  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 for the Real-Time Clock associated with

  the DA9063. There are currently no entries in this binding, however

  compatible = "dlg,da9063-rtc" should be added if a node is created.



- watchdog : This node defines settings for the Watchdog timer associated

  with the DA9063. There are currently no entries in this binding, however

  compatible = "dlg,da9063-watchdog" should be added if a node is created.





Example:



	pmic0: da9063@58 {

		compatible = "dlg,da9063"

		reg = <0x58>;

		interrupt-parent = <&gpio6>;

		interrupts = <11 IRQ_TYPE_LEVEL_LOW>;

		interrupt-controller;



		rtc {

			compatible = "dlg,da9063-rtc";

		};



		wdt {

			compatible = "dlg,da9063-watchdog";

		};



		regulators {

			DA9063_BCORE1: bcore1 {

				regulator-name = "BCORE1";

				regulator-min-microvolt = <300000>;

				regulator-max-microvolt = <1570000>;

				regulator-min-microamp = <500000>;

				regulator-max-microamp = <2000000>;

				regulator-boot-on;

			};

			DA9063_LDO11: ldo11 {

				regulator-name = "LDO_11";

				regulator-min-microvolt = <900000>;

				regulator-max-microvolt = <3600000>;

				regulator-boot-on;

			};

		};

	};
