v3:
Split patch 3/3 in v2 into 2 patches: one makes changes to acpi_video
and one adds the int3406 driver as suggested by Rafael. There should
be no functionality change compared to v2.

v2:
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.

  video / backlight: add two APIs for drivers to use
  video / backlight: remove the backlight_device_registered API
  Thermal: add INT3406 thermal driver

The first three patches in this series look OK to me, so

Acked-by: Rafael J. Wysocki <redacted>

for the [1-3/4].

That said it may be better if those three go in via ACPI.  I can put
them into a separate branch for Rui to pull from.

Please let me know what you think.

I have no problem with that.
