I am writing an SPI protocol driver and I find that my driver
is never probed.
I tried to add and call to of_register_spi_devices() in the
drivers/spi/mpc52xx_psc_spi.c::mpc52xx_psc_spi_of_probe() function,
without much effect besided that the DTS node is parsed but the driver probe
is not called, actually it complains about a modalias for my node is missing.
This is with kernel 2.6.29.3.
