commit 8a7f9894eff41652180825f5e9706ba29f72045b
Author: Shaunak Saha <shaunak.saha at intel.com>
Date: Tue Jun 7 00:05:00 2016 -0700
intel/apollolake: Add ASL code for DPTF
This patch adds the common ASL code for Intel
Apollolake platform. This is the basic ASL needed
to add support for DPTF controlled devices.
BUG = 53096
iTEST = Verify that the thermal zones are enumerated
under /sys/class/thermal. Navigate to
/sys/class/thermal, and verify that a thermal
zone of type TCPU exists there.
