From 92cf08c8f39869b619bd1129230df9e5174ba3f5 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Sat, 5 Feb 2011 12:20:23 +0000 Subject: [PATCH] Add PC87382 support This patch adds support for NSC PC87382 Super I/O. It is used in many Lenovo Notebooks as Docking LPC Switch. v2 because of: - Skip some empty files - Fix newlines in Kconfig and Makefile.inc - chip.h missed uart8250.h include - add the Kconfig option in sorted order Thanks to idwer on irc for pointing that out.
