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.
