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