From 988ee17fd2486415e8be4ebf49f57b5a1b97e685 Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Tue, 24 Nov 2015 14:11:57 -0600 Subject: [PATCH] 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, version 1.4.
