[PATCH V3 1/1] input: gpio-keys: add support for disable button from DT

From: Laxman Dewangan
Date: Wed Jan 13 2016 - 02:36:45 EST


Add support to disable the button from DT via status property
if given button is not supporting on given platforms.

This will help to re-use the existing dtsi file with status
enable/disable across platforms.
