Yes, this is right. =A0The psc_spi driver automatically registers all
spi children that it finds in the device tree onto the SPI bus.
Therefore registering an spi_driver() is the right thing to do.

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 pr=

is not called, actually it complains about a modalias for my node is

What do you see when you look in /sys/bus/spi/devices?  You should see
a directory for your device.  What do you see in /sys/bus/spi/drivers?
 In here you should see your driver.  If they are both there, then you
just have a problem matching your driver name to the device name.
