From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guenter Roeck Date: Mon, 30 Mar 2015 06:33:46 +0000 Subject: [lm-sensors] [PATCH 06/15] hwmon: (it87) Add support for IT8620E Message-Id: <1427697235-23566-7-git-send-email-linux@roeck-us.net> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org IT8620E is mostly compatible to IT7828F. Add generic support for it. IT8620E supports up to 6 fan tachometers and 6 pwm controls. Support for the 6th tachometer and for the additional pwm controls are addded in separate patches.
