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