+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 nodes, whose power is supplied by regulators,
+ which drivers are not yet supported. It will rely on regulator reset default
+ and use dummy regulator instead.
+
+Examples:
+
+.. code-block:: none
+
+ &usdhc3 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ barebox,allow-dummy-supply;
+
+ partition@0 {
+ label = "barebox";
+ reg = <0x0 0xe0000>;
+ };
+
+ partition@e0000 {
+ label = "barebox-environment";
+ reg = <0xe0000 0x20000>;
+ };
+ };
