+Power sequence DT bindings
+
+Each power sequence method has a corresponding "power-method" property string.
+This property shall be set in a subnode for a device. That subnode should also
+describe resourses which are specific to that power method.
+
+Do note, power sequences as such isn't encoded through DT. Instead those are
+implemented by each power method.
+
+Required subnode properties:
+- power-method: should contain the string for the power method to bind.
+
+	Supported power methods: None.
+
+Example:
+
+Note, the "clock" power method in this example isn't actually supported, but
+used to visualize how a childnode could be described.
