Re: need help getting SPI controller working on 405EX

Lorenz, thanks for the reply.

For getting spidev devices you have to add entries for an spidev device 
to your newly created spi-"bus". So what you are currently missing are 
the spidev child-nodes in the device tree.
As I'm currently cut off from some device to test, no guaranty that it 
will work, but your dts entry should look something like:

              SPI0: spi@ef600600 {
                  cell-index = <0>;
                  compatible = "ibm,spi-405ex", "ibm,spi";
                  reg = <ef600600 6>;
                  interrupts = <8 4>;
                  interrupt-parent = <&UIC0>;
                  mode = "cpu";

                  yourdevice@0 {
                      compatible = "spidev";
                      spi-max-frequency = <1000000>; /* what ever your 
max-freq. is */
                      reg = <0>; /* Chipselect-address */
                  };
              };

This did not appear to have any effect.

At least something similar worked for me some months ago (before we 
switched to a "real" driver for some custom peripheral).

Did this work on a 4xx PowerPC platform?  Or something else?  I've been
told that there is no SPI driver for 4xx.  If you have done this on 4xx
then I'm very interested.

Thanks,

Nathan
