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

Enable the Microchip PIC32 SPI driver. This driver can be used
to access the SPI NOR flash, MMC-over-SPI on platforms based on
Microchip PIC32 family devices.
config ROCKCHIP_SPI
bool "Rockchip SPI driver"
help
Enable the Rockchip SPI driver, used to access SPI NOR flash and
other SPI peripherals (such as the Chrome OS EC) on Rockchip SoCs.
This uses driver model and requires a device tree binding to
operate.
config SANDBOX_SPI
bool "Sandbox SPI driver"
depends on SANDBOX && DM
help
Enable SPI support for sandbox. This is an emulation of a real SPI
bus. Devices can be attached to the bus using the device tree
which specifies the driver to use. As an example, see this device
tree fragment from sandbox.dts. It shows that the SPI bus has a
single flash device on chip select 0 which is emulated by the driver
for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.
