Subject: [PATCH v2 0/3] Support INT3406 Display thermal device
Date: Wed, 13 Apr 2016 15:32:48 +0800 [thread overview]
Message-ID: <1460532771-22779-1-git-send-email-aaron.lu@intel.com> (raw)
The display thermal device represents the LED/LCD display panel
that may or may not include touch support. The main function of
the display thermal device is to allow control of the display
brightness in order to address a thermal condition or to reduce
power consumed by display device.
Due to the way this thermal device changes brightness level is said
to be deprecated so we are using the raw interface to do the actual
backlight change. This requires the backlight core support so two
new APIs are added and exported in patch 1/3. With this, the previous
API backlight_device_registered can be removed and this is done in
patch 2/3. Patch 3/3 adds the new int3406 thermal driver.
The 1st version is here:
http://thread.gmane.org/gmane.linux.acpi.devel/72619
This whole series should go through the thermal tree if applied.
