I have an SPI slave device. I want to build firmware for the Moto-Z play that enables the Moto-Z as an SPI master. I setup the firmware build and do a 'make menuconfig'. Under device drivers I setup SPI etc. When I search for 'SPI' I get alot of hits, including AIX_SPI0, A1X_SPI1, ARCH_CHIP_DEVICE_SPI, GREYBUS_SPI_PHY, etc. I have set SPI=y etc. but I don't know if these other settings are needed to get SPI to work. Any suggestions?
Thx
