+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>;
+  	};
+  };
