3config DM_SPI
4	bool "Enable Driver Model for SPI drivers"
5	depends on DM
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.

108	  which specifies the driver to use. As an example, see this device
109	  tree fragment from sandbox.dts. It shows that the SPI bus has a
110	  single flash device on chip select 0 which is emulated by the driver
111	  for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.
