  	help

  	  Enable driver model for SPI. The SPI slave interface
  	  (spi_setup_slave(), spi_xfer(), etc.) is then implemented by
  	  the SPI uclass. Drivers provide methods to access the SPI
  	  buses that they control. The uclass interface is defined in
  	  include/spi.h. The existing spi_slave structure is attached
  	  as 'parent data' to every slave on each bus. Slaves
  	  typically use driver-private data instead of extending the
  	  spi_slave structure.
