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.

87config SANDBOX_SPI
88	bool "Sandbox SPI driver"
89	depends on SANDBOX && DM
90	help
91	  Enable SPI support for sandbox. This is an emulation of a real SPI
92	  bus. Devices can be attached to the bus using the device tree
93	  which specifies the driver to use. As an example, see this device
94	  tree fragment from sandbox.dts. It shows that the SPI bus has a
95	  single flash device on chip select 0 which is emulated by the driver
96	  for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.
