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.
