The package makes it possible to create custom SPI buses via GPIO lines. This module is based on i2c-gpio-custom and allows to configure an SPI bus via GPIO lines and expose it to userspace without rebuilding the kernel. This is maily intended to connect microcontrollers and other simple SPI devices without making an ad-hoc kernel driver.

This is an SPI driver to register 1 to 4 custom SPI buses using
|
|
GPIO lines. Each bus can have up to 8 slaves.
|
|
The devices will be exposed to userspace as /dev/spidevX.X

This module is maily intended to interface microcontrollers
|
|
and other SPI devices without a specific kernel driver.
|
|
|
|
This support is also available as a module. If so, the module
|
|
will be called spi-gpio-custom.
