Matrix keymap support library

modulename: matrix-keymap.ko


Linux Kernel Configuration
└─>Device Drivers

└─>Matrix keymap support library
In linux kernel since version 3.1 (release Date: 2011-10-24)  
Say Y here if you are using a driver for an input
device that uses matrix keymap. This option is only
useful for out-of-tree drivers since in-tree drivers
select it automatically.

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called matrix-keymap.
