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.

There has a static checker warning:

After the PM support has been added to this driver, we get
a harmless warning when that support is disabled at compile
time:
drivers/thermal/tegra/soctherm.c:641:12: error: 'soctherm_resume' defined but not used [-Werror=unused-function]
static int soctherm_resume(struct device *dev)
This marks the two PM functions as __maybe_unused to shut up
the warning. This is preferred over adding an #ifdef around
them, as it is harder to get wrong, and provides better
compile-time coverage.

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.

When register sensors into thermal zone during initialization phase, it
reports error for IRQ imbalance enabling:
[ 2.040713] WARNING: at kernel/irq/manage.c:513
[ 2.040719] Modules linked in:
[ 2.040721]
[ 2.040729] CPU: 1 PID: 804 Comm: irq/33-hisi_the Not tainted 4.5.0-rc4+ #505

[ 2.040745] PC is at __enable_irq+0x74/0x84
[ 2.040749] LR is at __enable_irq+0x74/0x84
This warning is for IRQ imbalance enabling, which is caused by
enable_irq() twice. During sensor's initialization it tries to enable
IRQ, the driver will call thermal_zone_of_sensor_register() to bind
sensors and read sensor's temperature. But at this moment the flag
"data->irq_enabled" has been not initialized as correct state, so it
finally introduces the function enabled_irq() to be called twice. In
essentially this is caused by the flag "data->irq_enabled" is
inconsistent with real hardware IRQ enabling state.
So this patch is to fix this issue, firstly init "irq_enabled" flag
before binding sensors to thermal zone. Also change to use the function
irq_get_irqchip_state() to read back real interrupt line state.

In current code sensor driver registers all 4 sensors together and if
any of them has not bound to thermal zone successfully then driver will
return failure for driver's initialization. As a result, if DT binds
thermal zone with only one sensor, then the thermal driver will not work
well anymore.
So this patch is to fix this issue. It allows the thermal sensor driver
can register any number sensors at initialization phase, and fix up code
for other related code to skip related sensor's accessing if the sensor
has not been enabled in initialization phase.

Add support for hardware critical thermal limits to the
SOC_THERM driver. It use the Linux thermal framework to
create critical trip temp, and set it to SOC_THERM hardware.
If these limits are breached, the chip will reset, and if
appropriately configured, will turn off the PMIC.
This support is critical for safe usage of the chip.

In current of-thermal, the .set_trip_temp only support to
set trip_temp for SW. But some sensors support to set
trip_temp on hardware, so that can trigger interrupt,
shutdown or any other events.
This patch adds .set_trip_temp() callback in
thermal_zone_of_device_ops{}, so that the sensor device can
use it to set trip_temp on hardware.

Split most of the Tegra124 data and code into a Tegra124-specific

Split most of the fuse-related code into a fuse-related source file.
This is in preparation for adding a Tegra210-specific driver in a
future patch.
Beyond the maintainability improvements, this is intended to separate
chip-specific ATE and characterization-related hacks into chip-specific
files, in the hopes that they won't pollute code for other chips.

Get rid of T124-specific PDIV/HOTSPOT hack.
tegra-soctherm.c contained a hack to set the SENSOR_PDIV and
SENSOR_HOTSPOT_OFFSET registers - it just did two writes of
T124-specific opaque values. Convert these into a form that can be
substituted on a per-chip basis, and into structure fields that have
at least some independent meaning.

Both of these drivers can return NOTIFY_BAD, but this terminates
processing other callbacks that were registered later on the chain.
Since the driver did nothing to log the error it seems wrong to prevent
other interested parties from seeing it. E.g. neither of them had even
bothered to check the type of the error to see if it was a memory error
before the return NOTIFY_BAD.

"Three more bug fixes for 4.6

panic_on_oops a user space program can crash the system.
- An information leak with the /dev/sclp device.
- A use after free in the s390 PCI code"
