commit c7a11aad22aff123d77be7bd499bffbb29080932 Author: Alec Ari neotheuser@ymail.com Date: Sun Dec 29 23:48:38 2013 -0600
SuperIO: Add support for Nuvoton NCT6779D (Draft)
Adds support for the Nuvoton NCT6779D Super I/O (Not working) This is an entry draft and a lot of the datasheet I had difficulty understanding, therefor this commit should be thoroughly reviewed and verified by an experienced developer before pushing this into the official tree.
This commit will not work as-is and has not been tested.
