+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@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>;
+ };
+ }
+ }
