Subject: [lm-sensors] [PATCH] hwmon: (nct6775) NCT6791D and NCT6792D have an additional temperature source
Date: Fri, 30 Oct 2015 14:36:42 +0000 [thread overview]
Message-ID: <1446215802-15097-1-git-send-email-linux@roeck-us.net> (raw)
Both NCT6791D and NCT6792D permit selection of a 'virtual' temperature
register as temperature source. The virtual temperature registers are
registers 0xea to 0xef in bank 0 and can be written by software.
