From cab71b638f6bd9d8c7e6d7955d4527c5236177cb Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Sat, 5 Sep 2015 17:53:20 -0500 Subject: drivers/i2c/w83795: Add full support for core functions Add full support for fan control, fan monitoring, and voltage monitoring. Fan speeds and functions are configurable via each mainboard's devicetree.cb file. NOTE: This patch effectively rewrites large portions of the original driver. You may need to re-verify correct operation on your hardware if you were using the old driver code.
