From: Guenter Roeck Date: Thu, 15 Mar 2012 18:29:40 +0000 (-0700) Subject: Add support for fixed temperature registers supported by NCT6779D X-Git-Tag: nct6775-v0.9~48 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=69b5ecc72484fedcfe912b9d603d00b3b3c749a5;p=groeck-nct6775 Add support for fixed temperature registers supported by NCT6779D NCT6779D supports a fixed set of temperature registers in addition to the registers with dymanically configured source. Add support for it.
