From 44887c3e36821379d6091812b83e1b7ff9f9af53 Mon Sep 17 00:00:00 2001 From: Shaunak Saha Date: Tue, 7 Jun 2016 00:05:00 -0700 Subject: intel/common: Add ASL code for DPTF This patch adds the common ASL code for Intel platforms. This is the basic ASL needed to add support for DPTF controlled devices. We are moving these commmon ASL files to src/soc/intel/common/acpi as these are same codes used in all Intel platforms and hence no need to duplicate. BUG=chrome-os-partner:53096 TEST=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.
