[PATCH v4 5/6] document: devicetree: input: imx: i.mx snvs power device tree bindings

[Frank.Li at freescale.com]

From: Frank Li <Frank.Li at freescale.com>

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.
