Greetings, I am writing a driver for ARM Primecell Synchronous Serial Port (PL022) . I am using Linux Kernel 2.6.20.6. I am working on Customized version of ARM Versatile Board. Searched the Kernel Source but couldn't find any info for this Module. If anyone is working on it or has any reference/info, kindly can you share the same with me. I also saw few posts in the mailing list around May 2006 which says its already in the Source but couldn't find it. Thanks in advance Regards Gururaja
