Maxim Semiconductor Max77620 supports alarm interrupts when
its die temperature crosses 120C and 140C. These threshold
temperatures are not configurable.

Add thermal driver to register PMIC die temperature as thermal
zone sensor and capture the die temperature warning interrupts
to notifying the client.

This driver add thermal management support by enabling TMU (Thermal
Monitoring Unit) on QorIQ platform.

It's based on thermal of framework:
- Trip points defined in device tree.
- Cpufreq as cooling device registered in qoriq cpufreq driver.

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
(eeprom) device.

Add a skeleton driver with all the necessary abstractions so
a variety of qcom device families which support TSENS can
add driver extensions.

Also add the required device tree bindings which can be used
to describe the TSENS device in DT.

This change adds support for Intel BXT Whiskey Cove PMIC thermal
driver which is intended to handle the alert interrupts triggered
upon thermal trip point cross and notify the thermal framework
appropriately with the zone, temp, crossed trip and event details.

In some of platform, thermal sensors like NCT thermistors are
connected to the one of ADC channel. The temperature is read by
reading the voltage across the sensor resistance via ADC. Lookup
table for ADC read value to temperature is referred to get
temperature. ADC is read via IIO framework.

Add support for thermal sensor driver which read the voltage across
sensor resistance from ADC through IIO framework.

The Tango thermal driver provides support for the primitive temperature
sensor embedded in Tango chips since the SMP8758.

This sensor only generates a 1-bit signal to indicate whether the die
temperature exceeds a programmable threshold.

Move Tegra soctherm driver to tegra directory, it's easy to maintain
and add more new function support for Tegra platforms.
This will also help to split soctherm driver into common parts and
chip specific data related parts.

This adds support for the Mediatek thermal controller found on MT8173
and likely other SoCs.
The controller is a bit special. It does not have its own ADC, instead
it controls the on-SoC AUXADC via AHB bus accesses. For this reason
we need the physical address of the AUXADC. Also it controls a mux
using AHB bus accesses, so we need the APMIXEDSYS physical address aswell.

Add a generic thermal cooling device for devfreq, that is similar to
cpu_cooling.

The device must use devfreq.  In order to use the power extension of the
cooling device, it must have registered its OPPs using the OPP library.
