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. 15 16if DM_SPI 17 18config ALTERA_SPI 19 bool "Altera SPI driver" 20 help 21 Enable the Altera SPI driver.
