* Dialog DA9055 Power Management Integrated Circuit (PMIC)

DA9055 consists of a large and varied group of sub-devices (I2C Only):

Device			 Supply Names	 Description
------			 ------------	 -----------
da9055-gpio		:		: GPIOs
da9055-regulator	:		: Regulators
da9055-onkey		:		: On key
da9055-rtc		:		: RTC
da9055-hwmon		:		: ADC
da9055-watchdog		:		: Watchdog

The CODEC device in DA9055 has a separate, configurable I2C address and so
is instantiated separately from the PMIC.

For details on accompanying CODEC I2C device, see the following:
Documentation/devicetree/bindings/sound/da9055.txt

======

Required properties:
- compatible : Should be "dlg,da9055-pmic"
- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
- interrupts: IRQ line info for da9055 chip.
- interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
- #interrupt-cells: Should be 1, is the local IRQ number for da9055.

Sub-nodes:
- regulators : Contain the regulator nodes. The DA9055 regulators are
  bound using their names as listed below:

    buck1     : regulator BUCK1
    buck2     : regulator BUCK2
    ldo1      : regulator LDO1
    ldo2      : regulator LDO2
    ldo3      : regulator LDO3
    ldo4      : regulator LDO4
    ldo5      : regulator LDO5
    ldo6      : regulator LDO6

  The bindings details of individual regulator device can be found in:
  Documentation/devicetree/bindings/regulator/regulator.txt


Example:

	pmic: da9055-pmic@5a {
		compatible = "dlg,da9055-pmic";
		reg = <0x5a>;
		interrupt-parent = <&intc>;
		interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
		interrupt-controller;
		#interrupt-cells = <1>;

		regulators {
			buck1: BUCK1 {
				regulator-min-microvolt = <725000>;
				regulator-max-microvolt = <2075000>;
			};
			buck2: BUCK2 {
				regulator-min-microvolt = <925000>;
				regulator-max-microvolt = <2500000>;
			};
			ldo1: LDO1 {
				regulator-min-microvolt = <900000>;
				regulator-max-microvolt = <3300000>;
			};
		};
	};
