NAME

       struct_spi_driver - Host side "protocol" driver

SYNOPSIS

       struct spi_driver {
	 const struct spi_device_id * id_table;
	 int (* probe) (struct spi_device *spi);
	 int (* remove) (struct spi_device *spi);
	 void (* shutdown) (struct spi_device *spi);
	 int (* suspend) (struct spi_device *spi, pm_message_t mesg);
	 int (* resume) (struct spi_device *spi);
	 struct device_driver driver;
       };

MEMBERS

       id_table
	   List of SPI devices supported by this driver

       probe
	   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.

       remove
	   Unbinds this driver from the spi device

       shutdown
	   Standard shutdown callback used during system state transitions such as powerdown/halt and kexec

       suspend
	   Standard suspend callback used during system state transitions

       resume
	   Standard resume callback used during system state transitions

       driver
	   SPI device drivers should initialize the name and owner field of this structure.

DESCRIPTION

       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.
