commit 05b028ceaab92e779fdf7c807dacbd9cee19f6f2 Author: Shilpa Sreeramalu shilpa.sreeramalu@intel.com Date: Mon Jun 22 21:54:51 2015 +0530
kunimitsu: Enable and support for DPTF
This patch includes the DPTF specific ASL files in the main DSDT definition and enables the CPU thermal participant device in the device tree. It also enables the DPTF flag in the global NVS table.It also adds the ASL settings specfic to the mainboard.
BRANCH=None BUG=chrome-os-partner:40855 TEST=Built for kunimitsu board. Tested to see that the thermal devices and the participants are enumerated and can be seen in the /sys/bus/platform/devices. Also checked the temperature readings of the cooling devices and the thermal zones enumerated in the /sys/class/thermal.
