When you keep working on it, you can also look into that tree: http://git.pengutronix.de/?p=mgr/linux.git;a=shortlog;h=refs/heads/v3.11/topic/mc13xxx I currently have no time and no capable hardware on my desk to keep working on this. But it would be great if this code will not keep rotting any further. Thanks, Michael
