spi_driver Struct Reference

#include <spi.h>

List of all members.

Detailed Description

struct spi_driver - Host side "protocol" driver : Binds this driver to the spi device. Drivers can verify that the device is actually present, and may need to configure characteristics (such as bits_per_word) which weren't needed for the initial configuration done during system setup. : Unbinds this driver from the spi device : Standard shutdown callback used during system state transitions such as powerdown/halt and kexec : Standard suspend callback used during system state transitions : Standard resume callback used during system state transitions : SPI device drivers should initialize the name and owner field of this structure.

This represents the kind of device driver that uses SPI messages to interact with the hardware at the other end of a SPI link. It's called a "protocol" driver because it works through messages rather than talking directly to SPI hardware (which is what the underlying SPI controller driver does to pass those messages). These protocols are defined in the specification for the device(s) supported by the driver.

As a rule, those device protocols represent the lowest level interface supported by a driver, and it will support upper level interfaces too. Examples of such upper levels include frameworks like MTD, networking, MMC, RTC, filesystem character device nodes, and hardware monitoring.
