[PATCH 4/4] Input: pmic8xxx-keypad - update DT bindings documentation
From: Ivan T. Ivanov
Date: Tue Oct 07 2014 - 05:51:54 EST
Fix incorrect dimensions for 'debonce' and 'scan-delay' times.
Now they represent what driver really expect. Add possible
time quants for 'debonce', 'scan-delay' and 'row-hold' times.
Update bindings example.
