+SPI Driver
+**********
+
+The Serial Peripheral Interface (SPI) bus drivers should use the
+`SPI bus framework
+<https://git.rtems.org/rtems/tree/cpukit/dev/include/dev/spi/spi.h>`_.
+For
+example drivers see the
+`Atmel SAM SPI driver <https://git.rtems.org/rtems/tree/c/src/lib/libbsp/arm/atsam/spi/atsam_spi_bus.c>`_
+and the
+`SPI framework test <https://git.rtems.org/rtems/tree/testsuites/libtests/spi01/init.c>`_.
+
+The user API is compatible to the
+`Linux SPI user-space API <https://www.kernel.org/doc/Documentation/spi/spidev>`_.
