Linux Kernel Configuration
└─>Device Drivers
└─>SPI support
└─>SPI_MASTER
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If your system has an master-capable SPI controller (which
provides the clock and chipselect), you can enable that
controller and the protocol drivers for the SPI slave chips
that are connected.
