* Dialog DA9062 Power Management Integrated Circuit (PMIC)



DA9062 consists of a large and varied group of sub-devices:



Device                   Supply Names    Description

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

da9062-watchdog         :               : Watchdog Timer



======



Required properties:



- compatible : Should be "dlg,da9062".

- 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.

- 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 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.



- watchdog: This node defines the settings for the watchdog driver associated

  with the DA9062 PMIC. The compatible = "dlg,da9062-watchdog" should be added

  if a node is created.





Example:



	pmic0: da9062@58 {

		compatible = "dlg,da9062";

		reg = <0x58>;

		interrupt-parent = <&gpio6>;

		interrupts = <11 IRQ_TYPE_LEVEL_LOW>;

  The regulator-compatible property of regulator should initialized with string

to get matched with their hardware counterparts as follow:



	-LDOn 	:	for LDOs, where n can lie in range 1 to 26.

		 	example: LDO1, LDO2, LDO26.

	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 9.

  Regulators which can be turned off during system suspend:

	-LDOn	:	2, 6-8, 10-12, 14-16,

	-BUCKn	:	1-4.

  Use standard regulator bindings for it ('regulator-off-in-suspend').



  LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable

  control. To turn this feature on this property must be added to the regulator
