there are three concepts represent backlight in int3406_thermal driver.
1. the raw brightness value from native graphics driver.
2. the percentage numbers from ACPI _BCL control method.
3. the consecutive numbers represent cooling states.
int3406_thermal driver
1. uses value from DDDL/DDPC as the lower/upper limit, which is consistent
with ACPI _BCL control methods.
2. reads current and maximum brightness from the native graphics driver.
3. expose them to thermal sysfs I/F
This patch fixes the code that switches between the raw brightness value
and the cooling state, which results in bogus value in thermal sysfs I/F.

Using the TSDSS flag to determine whether the thermal sensor is
enabled is problematic. Broadwell-DE (Xeon D-1500) does not support
dynamic shutdown and the TSDSS flag always reads 0 (contrary to the
current datasheet). Even on hardware supporting dynamic shutdown, the
driver does nothing to configure it, and the dynamic shutdown state
should not prevent the driver from loading. The ETS flag itself
indicates whether the thermal sensor is enabled, so use it instead of
the TSDSS flag on all hardware platforms.

thermal_zone_device_register()
Reorder error handling code in order to fix some resources leaks in some
cases:
- 'tz' would leak if 'thermal_zone_create_device_groups()' fails
- memory allocated by 'thermal_zone_create_device_groups()' would leak
if 'device_register()' fails
With this patch, we now have 2 error handling paths: one before
'device_register()', and one after it.
This is needed because some resources are released in 'thermal_release()'.

Temperature (TEMP) register is 9 bits wide. Values above 0x100 (78
degrees C) are plausible, so don't mask out the topmost bit. And the

Pull thermal management updates from Zhang Rui:
- Improve thermal cpu_cooling interaction with cpufreq core.
The cpu_cooling driver is designed to use CPU frequency scaling to
avoid high thermal states for a platform. But it wasn't glued really
well with cpufreq core.
For example clipped-cpus is copied from the policy structure and its
much better to use the policy->cpus (or related_cpus) fields directly
as they may have got updated. Not that things were broken before this
series, but they can be optimized a bit more.
This series tries to improve interactions between cpufreq core and
cpu_cooling driver and does some fixes/cleanups to the cpu_cooling
driver. (Viresh Kumar)

Since all second level thermal IRQs are consumed by the same
device(bxt_wcove_thermal), there is no need to expose them as separate
interrupts. We can just export only the first level IRQs for thermal and
let the device(bxt_wcove_thermal) driver handle the second level IRQs
based on thermal interrupt status register. Also, just using only the
first level IRQ will eliminate the bug involved in requesting only the
second level IRQ and not explicitly enable the first level IRQ. For
more info on this issue please read the details at,
https://lkml.org/lkml/2017/2/27/148
This patch also makes relevant change in bxt_wcove_thermal driver to use

Use the new helper for reusing a device-tree node of another device
instead of managing the node references explicitly.
This also makes sure that the new of_node_reuse flag is set if the
device is ever reprobed, something which specifically now avoids driver
core from attempting to claim any pinmux resources already claimed by
the parent device.

The thermal child device reuses the parent MFD-device device-tree node
when registering a thermal zone, but did not take a reference to the
node.
This leads to a reference imbalance, and potential use-after-free, when
the node reference is dropped by the platform-bus device destructor
(once for the child and later again for the parent).
Fix this by dropping any reference already held to a device-tree node
and getting a reference to the parent's node which will be balanced on
reprobe or on platform-device release, whichever comes first.
Note that simply clearing the of_node pointer on probe errors and on
driver unbind would not allow the use of device-managed resources as
specifically thermal_zone_of_sensor_unregister() claims that a valid
device-tree node pointer is needed during deregistration (even if it
currently does not seem to use it).

The cpu_cooling driver keeps two tables:
- freq_table: table of frequencies in descending order, built from
policy->freq_table.
- power_table: table of frequencies and power in ascending order, built
from OPP table.
If the OPPs are used for the CPU device then both these tables are
actually built using the OPP core and should have the same frequency
entries. And there is no need to keep separate tables for this.
Lets merge them both.
Note that the new table is in descending order of frequencies and so the
'for' loops were required to be fixed at few places to make it work.
