The thermal driver is standalone driver which is used to enable
thermal sensors, so it can be used with any cooling device and
should not bind with CPU cooling device driver.

This original patch is suggested by Amit Kucheria; so it's to
polish the dependency in Kconfig, and remove the dependency with
CPU_THERMAL.

TSENS is Qualcomms' thermal temperature sensor device. It
supports reading temperatures from multiple thermal sensors
present on various QCOM SoCs.
Calibration data is generally read from a non-volatile memory

a variety of qcom device families which support TSENS can
add driver extensions.

Also add the required device tree bindings which can be used

The power allocator governor is a thermal governor that controls system
and device power allocation to control temperature.  Conceptually, the
implementation divides the sustainable power of a thermal zone among
all the heat sources in that zone.

This governor relies on "power actors", entities that represent heat
sources.  They can report current and maximum power consumption and
can set a given maximum power consumption, usually via a cooling
device.

The governor uses a Proportional Integral Derivative (PID) controller
driven by the temperature of the thermal zone.  The output of the
controller is a power budget that is then allocated to each power
actor that can have bearing on the temperature we are trying to
control.  It decides how much power to give each cooling device based
on the performance they are requesting.  The PID controller ensures
that the total power budget does not exceed the control temperature.

In Intel Quark SoC X1000, there is one on-die digital temperature sensor(DTS).
The DTS offers both hot & critical trip points.

However, in current distribution of UEFI BIOS for Quark platform, only
critical trip point is configured to be 105 degree Celsius (based on Quark
SW ver1.0.1 and hot trip point is not used due to lack of IRQ.

There is no active cooling device for Quark SoC, so Quark SoC thermal
management logic expects Linux distro to orderly power-off when temperature
of the DTS exceeds the configured critical trip point.

Kernel param "polling_delay" in milliseconds is used to control the frequency
the DTS temperature is read by thermal framework. It defaults to 2-second.
To change it, use kernel boot param "intel_quark_dts_thermal.polling_delay=X".

User interacts with Quark SoC DTS thermal driver through sysfs via:
/sys/class/thermal/thermal_zone0/

For example:
 - to read DTS temperature
   $ cat temp
 - to read critical trip point
   $ cat trip_point_0_temp
 - to read trip point type
   $ cat trip_point_0_type
 - to emulate temperature raise to test orderly shutdown by Linux distro
   $ echo 105 > emul_temp
