Hi List, this patch adds support for the NSC PC87392 Super I/O. It is used in Lenovo Docking Stations as Super I/O chip. v2 because of: - The patch added some empty files - missing newlines in Kconfig and Makefile.inc - add the Kconfig option in sorted order Thanks to idwer on irc for pointing that out.
