* Dialog Semiconductor SLG51000 Voltage Regulator



Required properties:

- compatible : Should be "dlg,slg51000" for SLG51000

- reg : Specifies the I2C slave address.

- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.

  These entries are required if regulators are enabled for a device.

  An absence of these properties can cause the regulator registration to fail.

  If some of input supply is powered through battery or always-on supply then

  also it is required to have these parameters with proper node handle of always

  on power supply.

    vin3-supply: Input supply for ldo3

    vin4-supply: Input supply for ldo4

    vin5-supply: Input supply for ldo5

    vin6-supply: Input supply for ldo6

    vin7-supply: Input supply for ldo7



Optional properties:

- interrupt-parent : Specifies the reference to the interrupt controller.

- interrupts : IRQ line information.

- dlg,cs-gpios : Specify a valid GPIO for chip select



Sub-nodes:

- regulators : This node defines the settings for the regulators.

  The content of the sub-node is defined by the standard binding

  for regulators; see regulator.txt.



  The SLG51000 regulators are bound using their names listed below:

    ldo1

    ldo2

    ldo3

    ldo4

    ldo5

    ldo6

    ldo7



Optional properties for regulators:

- enable-gpios : Specify a valid GPIO for platform control of the regulator.



Example:

	pmic: slg51000@75 {

		compatible = "dlg,slg51000";

		reg = <0x75>;



		regulators {

			ldo1 {

			        regulator-name = "ldo1";

			        regulator-min-microvolt = <2400000>;

			        regulator-max-microvolt = <3300000>;

			};



			ldo2 {

			        regulator-name = "ldo2";

			        regulator-min-microvolt = <2400000>;

			        regulator-max-microvolt = <3300000>;

			};



			ldo3 {

			        regulator-name = "ldo3";

			        regulator-min-microvolt = <1200000>;

			        regulator-max-microvolt = <3750000>;

			};



			ldo4 {

			        regulator-name = "ldo4";

			        regulator-min-microvolt = <1200000>;

			        regulator-max-microvolt = <3750000>;

			};



			ldo5 {

			        regulator-name = "ldo5";

			        regulator-min-microvolt = <500000>;

			        regulator-max-microvolt = <1200000>;

			};



			ldo6 {

			        regulator-name = "ldo6";

			        regulator-min-microvolt = <500000>;

			        regulator-max-microvolt = <1200000>;

			};



			ldo7 {

			        regulator-name = "ldo7";

			        regulator-min-microvolt = <1200000>;

			        regulator-max-microvolt = <3750000>;

			};

		};

	};
