From 4ee07157d690b1b824328a473816a371130de6f2 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 25 Mar 2015 23:26:28 -0700 Subject: [PATCH] hwmon: (it87) Add support for IT8790E IT8790E is a super-IO chip with three fan tachometers. It is mostly compatible to IT8728F, but only supports three fan tachometers instead of five.
