5 ----------------
6 Nodes that describe devices which have wakeup capability may contain a
7 "wakeup-source" boolean property.
9 If the device is marked as a wakeup-source, interrupt wake capability depends
10 on the device specific "interrupt-names" property. If no interrupts are labeled
14 However if a device has a dedicated interrupt as the wakeup source, then it
16 cases only that interrupt can be used as a wakeup interrupt.
18 While various legacy interrupt names exist, new devices should use "wakeup" as
