 - regulator-state-[mem/disk] node has following common properties:
 	- regulator-on-in-suspend: regulator should be on in suspend state.
 	- regulator-off-in-suspend: regulator should be off in suspend state.
-	- regulator-suspend-microvolt: regulator should be set to this voltage
-	  in suspend.
+	- regulator-suspend-min-microvolt: minimum voltage may be set in
+	  suspend state.
+	- regulator-suspend-max-microvolt: maximum voltage may be set in
+	  suspend state.
+	- regulator-suspend-microvolt: the default voltage which regulator
+	  would be set in suspend. This property is now deprecated, instead
+	  setting voltage for suspend mode via the API which regulator
+	  driver provides is recommended.
+	- regulator-changeable-in-suspend: whether the default voltage and
+	  the regulator on/off in suspend can be changed in runtime.
 	- regulator-mode: operating mode in the given suspend state.
 	  The set of possible operating modes depends on the capabilities of
 	  every hardware so the valid modes are documented on each regulator
