+Voltage/Current Regulators
+==========================
+
+In addition to the upstream bindings, another property is added:
+
+Optional properties:
+- ``barebox,allow-dummy-supply`` : A property to allow usage of dummy power
+  regulator. This can be added to regulator nodes, whose drivers are not yet
+  supported. It will rely on regulator reset defaults and use of dummy regulator
+  instead.
+
+Examples:
+
+.. code-block:: none
+
+  pmic at 58 {
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_pmic>;
+	compatible = "dlg,da9063";
+	reg = <0x58>;
+
+	regulators {
+		barebox,allow-dummy-supply;
+
+		vddcore_reg: bcore1 {
+			regulator-min-microvolt = <730000>;
+			regulator-max-microvolt = <1380000>;
+		};
+
+		vddsoc_reg: bcore2 {
+			regulator-min-microvolt = <730000>;
+			regulator-max-microvolt = <1380000>;
+		};
+	}
+  }
