| 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. | |

| 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. | |
