I've updated the device tree for my Kilauea (405EX) board but am not sure I have everything correct. Also, any pointers to sample/test code incorporating a spi protocol driver would be incredibly helpful. I'm very new to device driver programming and don't really know what I'm doing yet. I seem to be getting the spi_ppc4xx and spi_bitbang modules loaded, but am unsure how to verify proper initialization and what next steps I need to follow in order to develop and associate a protocol driver. I'd like to start quite simply - some test routines that would drive data over the SPI connector on my Kilauea, using a spare GPIO pin as a chip select. I've got a logic analyzer from which to verify the results. I've been reading through all the documentation I can find but am a little stuck. A concrete example with a SPI protocol driver would be quite useful.
