That's a good thing, except for being on such an old kernel! When NXP was part of Philips, open source Linux driver code seemed to be a conceptual problem to management. Evidently, becoming NXP allowed various necessary changes ... conforming to the GPL should always have been a business *requirement* for drivers written to the Linux programming interfaces. > We are working to port same to latest kernel 2.6.20 , very soon I'll > upload the Host Stack to sourceforge, Device Stack yet to start porting. It'd be much better to have the host stack merged into the mainstream kernel ... now working on 2.6.22 integration. I understand that you'll want to have your QA/Validation teams make sure that your customers can be told "use this kernel, it works". The kernel programming interfaces evolve over time, and it's a good thing if your customers can have more current options. > The Device stack may be different from the Gadget stack.
