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 {

		compatible = "fsl,sec-v4.0-pwrkey";

		regmap = <&snvs>;

		interrupts = <0 4 0x4>

	        linux,keycode = <116>; /* KEY_POWER */

		wakeup;

	};
