From c9c29264b8c41bc2462d9a9fd2240b5c9350cdc0 Mon Sep 17 00:00:00 2001 From: Gergely Kiss Date: Wed, 27 Dec 2017 15:19:16 +0100 Subject: superio/ite/it8623e: add support for SIO chip ITE IT8623E MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change adds basic support for the SuperIO chip ITE IT8623E. Due to the lack of a datasheet, defaults are shown as "not available (NA)" in superiotool's register dump. LDNs defined in it8623e.h are definitely correct and working as expected.
