I'm trying to build a simple example program that allows me to test connection to
an SPI device I've wired up to my SABRESD.
Unlike I2C (which has /dev/i2c-0, /dev/i2c-1, and /dev/i2c-2), SPI doesn't have
an equivalent nodes in /dev.
It appears to have been built in the kernel tree; however, I don't see any
support for it under /dev.
Has anyone worked with SPI hooked to a device that is not MTD?
What's the trick?
