menu "SPI Support" 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. 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. if DM_SPI config ALTERA_SPI bool "Altera SPI driver" help Enable the Altera SPI driver.

This uses driver model and requires a device tree binding to operate. config SANDBOX_SPI bool "Sandbox SPI driver" depends on SANDBOX && DM help Enable SPI support for sandbox. This is an emulation of a real SPI bus. Devices can be attached to the bus using the device tree which specifies the driver to use. As an example, see this device tree fragment from sandbox.dts. It shows that the SPI bus has a single flash device on chip select 0 which is emulated by the driver for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c. spi@0 { #address-cells = <1>; #size-cells = <0>; reg = <0>; compatible = "sandbox,spi"; cs-gpios = <0>, <&gpio_a 0>; flash@0 { reg = <0>; compatible = "spansion,m25p16", "sandbox,spi-flash"; spi-max-frequency = <40000000>; sandbox,filename = "spi.bin"; }; }; config TEGRA114_SPI bool "nVidia Tegra114 SPI driver" help Enable the nVidia Tegra114 SPI driver. This driver can be used to access the SPI NOR flash on platforms embedding this nVidia Tegra114 IP core. This controller is different than the older SoCs SPI controller and also register interface get changed with this controller. config TEGRA20_SFLASH bool "nVidia Tegra20 Serial Flash controller driver" help Enable the nVidia Tegra20 Serial Flash controller driver.
