Hi Guys, I am doing a very interesting stuff of porting Linux to a PPC Board. The board is now operational with all the basic functionality and I am able to do things like access the tty through serial, load/unload modules. Now, I have to start of and write some drivers for CPLD based devices and few other simple drivers for controlling simple hardware. I have worked on char, block drivers till now and not worked on any other models. In the recent past, I have observed that there are other driver models that are applicable based on the context. In such models, I am aware of platform drivers, class drivers(non-usb) but I am not sure about when to use them I have read though some of the docs in 'driver-models' folder. I am not much clean on the application of these driver models. I have browsed through code in ep9312 as well. but, I though it would give be a better picture if I listen form you guys. What is application of these driver models? Are there other driver models other than platform, class? If I want to write a simple driver to control different small sub-systems on my PPC brd, I am planning to use char model/ioctl commands to accomplish this. Is there a better way to do it. I have plans to submit my code to kernel, so please let me know what is more appropriate.
