-Required properties:
-
-- compatible:	must be "dlg,da9210"
-- reg:		the i2c slave address of the regulator. It should be 0x68.
-
-Optional properties:
-
-- interrupts:	a reference to the DA9210 interrupt, if available.
-
-Any standard regulator properties can be used to configure the single da9210
-DCDC.
-
-Example:
-
-	da9210@68 {
-		compatible = "dlg,da9210";
-		reg = <0x68>;
-
-		interrupt-parent = <...>;
-		interrupts = <...>;

-		regulator-min-microvolt = <300000>;
-		regulator-max-microvolt = <1570000>;
-		regulator-min-microamp = <1600000>;
-		regulator-max-microamp = <4600000>;
-		regulator-boot-on;
