menuconfig SPI bool "SPI Support" if SPI 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.
