It depends on the hardware, this is what I have enabled on an AMD MoBo: ~ $ grep SPI /usr/src/linux/.config CONFIG_UNINLINE_SPIN_UNLOCK=y CONFIG_MUTEX_SPIN_ON_OWNER=y CONFIG_RWSEM_SPIN_ON_OWNER=y CONFIG_LOCK_SPIN_ON_OWNER=y CONFIG_ARCH_USE_QUEUED_SPINLOCKS=y CONFIG_QUEUED_SPINLOCKS=y # CONFIG_INET6_ESPINTCP is not set CONFIG_SCSI_SPI_ATTRS=y CONFIG_SPI=y CONFIG_SPI_MASTER=y # CONFIG_SPI_MEM is not set # SPI Master Controller Drivers # CONFIG_SPI_ALTERA is not set # CONFIG_SPI_AXI_SPI_ENGINE is not set # CONFIG_SPI_BITBANG is not set # CONFIG_SPI_CADENCE is not set # CONFIG_SPI_DESIGNWARE is not set # CONFIG_SPI_NXP_FLEXSPI is not set # CONFIG_SPI_GPIO is not set # CONFIG_SPI_MICROCHIP_CORE is not set # CONFIG_SPI_MICROCHIP_CORE_QSPI is not set # CONFIG_SPI_LANTIQ_SSC is not set # CONFIG_SPI_OC_TINY is not set # CONFIG_SPI_PXA2XX is not set # CONFIG_SPI_ROCKCHIP is not set # CONFIG_SPI_SC18IS602 is not set # CONFIG_SPI_SIFIVE is not set # CONFIG_SPI_MXIC is not set # CONFIG_SPI_XCOMM is not set # CONFIG_SPI_XILINX is not set # CONFIG_SPI_ZYNQMP_GQSPI is not set CONFIG_SPI_AMD=m # SPI Multiplexer support # CONFIG_SPI_MUX is not set # SPI Protocol Masters # CONFIG_SPI_SPIDEV is not set # CONFIG_SPI_LOOPBACK_TEST is not set # CONFIG_SPI_TLE62X0 is not set # CONFIG_SPI_SLAVE is not set CONFIG_SPI_DYNAMIC=y # SPI GPIO expanders # end of SPI GPIO expanders # CONFIG_SENSORS_LTC2947_SPI is not set # CONFIG_MFD_DA9052_SPI is not set # CONFIG_MFD_MC13XXX_SPI is not set # CONFIG_MFD_TPS65912_SPI is not set # CONFIG_MFD_ARIZONA_SPI is not set # CONFIG_MFD_WM831X_SPI is not set # CONFIG_SND_SPI is not set # SPI RTC drivers CONFIG_RTC_I2C_AND_SPI=y # SPI and I2C RTC drivers # CONFIG_HWSPINLOCK is not set
