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.
