MODULE_SPI_DRIVER(9) Serial Peripheral Interface (S MODULE_SPI_DRIVER(9)NAME
module_spi_driver - Helper macro for registering a SPI driver
SYNOPSIS
module_spi_driver(__spi_driver);
ARGUMENTS
__spi_driver
spi_driver struct
DESCRIPTION
Helper macro for SPI drivers which do not do anything special in module init/exit. This eliminates a lot of boilerplate. Each module may
only use this macro once, and calling it replaces module_init and module_exit

spi -- introduction to machine-independent SPI bus support and drivers
SYNOPSIS
spi* at mainbus?
Other attachments are machine-dependent and will depend on the bus topology of your system. See intro(4) for your system for more informa-
tion.
DESCRIPTION
NetBSD includes a machine dependent SPI (Serial Peripheral Interface) bus subsystem, and several different machine-independent SPI device
drivers.
Your system may support additional machine-dependent SPI devices. Consult your system's intro(4) for additional information.
SPI is a 4-wire synchronous full-duplex serial bus. Some systems provide support for Microwire, which is Philips' name for a strict subset
of SPI, with more rigidly defined signaling. Therefore, Microwire devices are also supported by the SPI framework.
Note that when referencing SPI devices in a config(1) file, the 'slave' must be provided, as SPI lacks any way to automatically probe
devices.
HARDWARE
NetBSD includes the following machine-independent SPI drivers
m25p STMicroelectronics M25P family of NOR flash devices.
tm121temp Texas Instruments TMP121 temperature sensor.
SEE ALSO m25p(4), tm121temp(4)HISTORY
The machine-independent SPI framework was written by Garrett D'Amore for the Champaign-Urbana Community Wireless Network Project (CUWiN), and
appeared in NetBSD 4.0.
