^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) Specifying wakeup capability for devices
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) ============================================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) Any device nodes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) ----------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Nodes that describe devices which has wakeup capability must contain an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) "wakeup-source" boolean property.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) Also, if device is marked as a wakeup source, then all the primary
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) interrupt(s) can be used as wakeup interrupt(s).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) However if the devices have dedicated interrupt as the wakeup source
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) then they need to specify/identify the same using device specific
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) interrupt name. In such cases only that interrupt can be used as wakeup
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) interrupt.
