+title: Wakeup sources
+
+description: >
+  Nodes that describe devices which have wakeup capability may contain a
+  "wakeup-source" boolean property.
+
+  If the device is marked as a wakeup-source, interrupt wake capability depends
+  on the device specific "interrupt-names" property. If no interrupts are labeled
+  as wake capable, then it is up to the device to determine which interrupts can
+  wake the system.
+
+  However if a device has a dedicated interrupt as the wakeup source, then it
+  needs to specify/identify it using a device specific interrupt name. In such
+  cases only that interrupt can be used as a wakeup interrupt.
+
+  While various legacy interrupt names exist, new devices should use "wakeup" as
+  the canonical interrupt name.
