The snvs-pwrkey is designed to enable POWER key function which controlled
by SNVS ONOFF. the driver can report the status of POWER key and wakeup
system if pressed after system suspend.

+System ON/OFF key driver

+  The snvs-pwrkey is designed to enable POWER key function which controlled
+  by SNVS ONOFF, the driver can report the status of POWER key and wakeup
+  system if pressed after system suspend.

+      Value type: <prop_encoded-array>
+      Definition: The SNVS ON/OFF interrupt number to the CPU(s).
+
+  - linux,keycode:
+      Usage: option
+      Value type: <int>
+      Definition: Keycode to emit, KEY_POWER by default.

+  - wakeup:
+      Usage: option
+      Value type: <boo>
