From 42a116b68ea468e32bb37aa333e53eb9c552a6c7 Mon Sep 17 00:00:00 2001
From: Timothy Pearson <tpearson@raptorengineeringinc.com>
Date: Tue, 24 Nov 2015 14:11:57 -0600
Subject: [PATCH 24/45] superio/winbond/w83667hg-a: Add support for W83667HG-A
The KGPE-D16 and KCMA-D8 use a Winbond W83667HG-A SuperIO. While
the Nuvoton NCT5572D is effectively the same core, and a close
enough match to get things working initially, the W83667HG-A
has a different LDN mapping and several extra features that
require a separate support driver.
Clone the Nuvoton NCT5572D and modify according to the W83667HG-A
datasheet.
