+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.
+
+ - compatible:
+ Usage: required
+ Value type: <string>
+ Definition: Mush include "fsl,sec-v4.0-pwrkey".
+
+ - interrupts:
+ Usage: required
+ 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>
+ Definition: Button can wake-up the system.
+
+ - regmap:
+ Usage: required:
+ Value type: <phandle>
+ Definition: this is phandle to the register map node.
+
+EXAMPLE:
+ snvs-pwrkey@0x020cc000 {

+ regmap = <&snvs>;
+ interrupts = <0 4 0x4>
+ linux,keycode = <116>; /* KEY_POWER */
