Hi Alan, We are now able to confirm that device ".name" and ".modalias" inside board configuration have got the same value.
Everything seems fine and correctly executed during boot sequence. We've made the driver as a loadable module. Then when we "modprobe" the module it correctly start/init and register. BUT definitely we never go through it's "probe" function. We are expecting a new physical driver that could be detected with the "iz listphy" userspace tool from Linux-zigbee (like a "wpan-phyX" interface). Is that ok ? Have you got any idea about what we are missing ? Maybe something to do on user side ? Have you got any idea of where we could find the task that "probe" existing or "loadable" driverS inside the kernel ? This way we could try to debug it to see if it parse all the declared SPI devices ?

Yes, that's why I clarified in the second email. I sent the wrong patch, but the idea is the same, substituting cc120 for spidev. I thought your previous email said cc2420. If that's the case, then there's already of course a driver for it and you just need to attach to it (similar to what I did in the patch I sent). If cc120 is a new device, then you'll need to write a driver for it. > Not yet successful but still working on.

Also see Documentation/networking/ieee802154.txt . For general information about making drivers, see Linux Device Drivers, 3rd Edition at http://lwn.net/Kernel/LDD3/ . Beyond that you'll need to read the code. Look at drivers which are similar to your device to see how they work.
