And then add

       { .compatible = "simple-bus", },

to your struct of_device_id array.

Yea, that works!  I hit the probe function.  Thanks very much Timur.  I 
would never have found that.

Experimentally, I've found that I don't need the "simple-bus" 
compatibility in the of_device_id array in the Elo DMA driver.  Any idea 
why?

Thanks again for all the help.  If you've got some time, could you explain 
why adding the "simple-bus" compatibility to the SOC node of the device 
tree was needed.  I _still_ (after fighting with them for over a year) 
don't get device trees.
