Maxim MAX1586 voltage regulator

Required properties:

- compatible: must be "maxim,max1586"

- reg: I2C slave address, usually 0x14

- v3-gain: integer specifying the V3 gain as per datasheet

           (1 + R24/R25 + R24/185.5kOhm)

- any required generic properties defined in regulator.txt

Example:

	i2c_master {

		max1586@14 {

			compatible = "maxim,max1586";

			reg = <0x14>;

			v3-gain = <1000000>;

			regulators {

				vcc_core: v3 {

					regulator-name = "vcc_core";

					regulator-compatible = "Output_V3";

					regulator-min-microvolt = <1000000>;

					regulator-max-microvolt = <1705000>;

					regulator-always-on;

				};

			};

		};

	};

Binding for Maxim MAX77802 regulators

This is a part of device tree bindings of MAX77802 multi-function device.

More information can be found in bindings/mfd/max77802.txt file.

The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)

regulators that can be controlled over I2C.

Following properties should be present in main device node of the MFD chip.

Optional node:

- regulators : The regulators of max77802 have to be instantiated

  under subnode named "regulators" using the following format.

	regulator-name {

		standard regulator constraints....

	};

	refer Documentation/devicetree/bindings/regulator/regulator.txt

The regulator node name should be initialized with a string to get matched

with their hardware counterparts as follow. The valid names are:

	-LDOn 	:	for LDOs, where n can lie in ranges 1-15, 17-21, 23-30

			and 32-35.

			example: LDO1, LDO2, LDO35.

	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 10.

			example: BUCK1, BUCK5, BUCK10.

Example:

	max77802@09 {

		compatible = "maxim,max77802";

		interrupt-parent = <&wakeup_eint>;

		interrupts = <26 0>;

		reg = <0x09>;

		#address-cells = <1>;

		#size-cells = <0>;

		regulators {

			ldo11_reg: LDO11 {

				regulator-name = "vdd_ldo11";

				regulator-min-microvolt = <1900000>;

				regulator-max-microvolt = <1900000>;

				regulator-always-on;

			};

			buck1_reg: BUCK1 {

				regulator-name = "vdd_mif";

				regulator-min-microvolt = <950000>;

				regulator-max-microvolt = <1300000>;

				regulator-always-on;

				regulator-boot-on;

			};

	};

	  and one current regulator 'CHARGER'. This is suitable for

	  Exynos-4x12 chips.
