commit edde7eb891e9d4e5baf7f67c104577f0b551dd95 Author: WANG Siyuan wangsiyuanbuaa@gmail.com Date: Tue Jun 23 22:43:03 2015 +0800
AMD Bettong: add fan control
1. Use enable_imc_thermal_zone to enable fan control. 2. The ACPI method ITZE works on Ubuntu 14.04 and Windows 7 but not works on Windows 8, so I dindn't use it. After this issue is fiexed, I'll add ACPI_ENABLE_THERMAL_ZONE in bettong/Kconfig. 3. TEST: fan control works on Bettong.
