Simon Glassf94a1be2015-02-05 21:41:35 -0700[diff] [blame]7 Enable driver model for SPI. The SPI slave interface
8 (spi_setup_slave(), spi_xfer(), etc.) is then implemented by
9 the SPI uclass. Drivers provide methods to access the SPI
10 buses that they control. The uclass interface is defined in
11 include/spi.h. The existing spi_slave structure is attached
12 as 'parent data' to every slave on each bus. Slaves
13 typically use driver-private data instead of extending the
14 spi_slave structure.

65 Enable SPI support for sandbox. This is an emulation of a real SPI
66 bus. Devices can be attached to the bus using the device tree
67 which specifies the driver to use. As an example, see this device
68 tree fragment from sandbox.dts. It shows that the SPI bus has a
69 single flash device on chip select 0 which is emulated by the driver
70 for "sandbox,spi-flash", which is in drivers/mtd/spi/sandbox.c.
