+ 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.
