commit 9981eb994df887b6e63c77e5456049ac08d8fe85 Author: Duncan Laurie dlaurie@chromium.org Date: Mon Jan 6 12:33:59 2014 -0800
baytrail: Updates for DPTF ACPI framework
- Remove some unused functions from CPU participant that were confusing the userland component since the CPU does not have an ACPI managed sensor.
- Guard the charger participant with an ifdef so it can be left out if not supported.
- Use the EC methods for setting auxiliary trip points and for handling the event when those trip points are crossed.
- Add _NTT _DTI _SCP methods for thermal sensors. I'm not clear if these are required or not but they seem to be expected by the other DPTF framework components.
BUG=chrome-os-partner:17279 BRANCH=rambi TEST=build and boot on rambi and load ESIF framework
