In linux kernel since version 3.1 (release Date: 2011-10-24)  
Say Y here to enable the matrix keyboard used by ChromeOS devices
and implemented on the ChromeOS EC. You must enable one bus option
(CROS_EC_I2C or CROS_EC_SPI) to use this.

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