* 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 {

			        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-min-microvolt = <500000>;
			        regulator-max-microvolt = <1200000>;

			        regulator-min-microvolt = <500000>;
			        regulator-max-microvolt = <1200000>;

			        regulator-name = "ldo7";
			        regulator-min-microvolt = <1200000>;
			        regulator-max-microvolt = <3750000>;
