+- regulator-state-mem sub-root node for Suspend-to-RAM mode
+  : suspend to memory, the device goes to sleep, but all data stored in memory,
+  only some external interrupt can wake the device.
+- regulator-state-disk sub-root node for Suspend-to-DISK mode
+  : suspend to disk, this state operates similarly to Suspend-to-RAM,
+  but includes a final step of writing memory contents to disk.
+- 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-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
+          device tree binding document.
+- regulator-initial-mode: initial operating mode. The set of possible operating
+  modes depends on the capabilities of every hardware so each device binding
+  documentation explains which values the regulator supports.
