4 The "Serial Peripheral Interface" is a low level synchronous
5 protocol. Chips that support SPI can have data transfer rates
6 up to several tens of Mbit/sec. Chips are addressed with a
7 controller and a chipselect. Most SPI slaves don't support
8 dynamic device discovery; some are even write-only or read-only.
10 SPI is widely used by microcontrollers to talk with sensors,
11 eeprom and flash memory, codecs and various other controller
12 chips, analog to digital (and d-to-a) converters, and more.
13 MMC and SD cards can be accessed using SPI protocol; and for
14 DataFlash cards used in MMC sockets, SPI must always be used.
16 SPI is one of a family of similar protocols using a four wire
17 interface (select, clock, data in, data out) including Microwire
18 (half duplex), SSP, SSI, and PSP. This driver framework should
19 work with most such devices and controllers.
24 bool "Enable Driver Model for SPI drivers"
27 Enable driver model for SPI. The SPI slave interface
28 (spi_setup_slave(), spi_xfer(), etc.) is then implemented by

30 buses that they control. The uclass interface is defined in
31 include/spi.h. The existing spi_slave structure is attached
32 as 'parent data' to every slave on each bus. Slaves
33 typically use driver-private data instead of extending the
