Add a no_irq_wake flag to struct tsens_plat_data to allow platforms
to control whether TSENS interrupts should be configured as wakeup
sources.
Create a new data_automotive structure and add compatible strings for
automotive TSENS variants (SA8775P, SA8255P) with wakeup interrupts
disabled.
Automotive platforms can enter a low-power parking suspend state where the
application processors and thermal mitigation paths are not active. In this
state, waking the system due to TSENS threshold interrupts does not enable
useful thermal action, but it does repeatedly break suspend residency and
increase battery drain.
Allow these automotive variants to keep TSENS monitoring enabled during
normal runtime while opting out of TSENS wakeup interrupts during suspend,
so the system can remain in low power until ignition/resume.

This change improves power management by using the standardized PM
framework for wake IRQ handling.
Move wake IRQ control to the PM suspend/resume path:
- store uplow/critical IRQ numbers in struct tsens_priv
- enable wake IRQs in tsens_suspend_common() when wakeup is allowed
- disable wake IRQs in tsens_resume_common()
- mark the device wakeup-capable during probe
This aligns TSENS wake behavior with suspend flow and avoids keeping
wake IRQs permanently enabled during runtime.

Extend the cooling device specifier parsing to support an optional
cooling device identifier (cdev_id).
Two formats are now supported:
- Legacy format:
<&cdev lower upper>
- Indexed format:
<&cdev cdev_id lower upper>
When the indexed format is used, both the device node and the
cdev_id must match in order to bind a cooling device to a thermal
zone. The legacy format continues to match on the device node only,
preserving backward compatibility.
Update the parsing logic accordingly to handle both formats and
extract the mitigation limits from the appropriate arguments.

The SoC Thermal Management Unit (TMU) is essential for proper operation
of the SoCs. Kernel should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.
Impact of making it default:
1. arm64 defconfig: No changes, already present in defconfig.
2. arm32: No changes, the driver is already selected by MACH_EXYNOS.
3. COMPILE_TEST builds: enable by default for arm32 or arm64 builds,
whenever ARCH_EXYNOS is selected. This has impact on build time and
feels logical, because if one selects ARCH_EXYNOS then probably by
default wants to build test it entirely. Kernels with COMPILE_TEST
are not supposed to be used for booting.

Invalid temperature measurements may be observed across the temperature
range specified in the device data sheet. The invalid temperature can
be read from any remote site and from any capture or report registers.
The invalid change in temperature can be positive or negative and the
resulting temperature can be outside the calibrated range, in which
case the TSR[ORL] or TSR[ORH] bit will be set.
Workaround:
Use the raising/falling edge threshold to filter out the invalid temp.
Check the TIDR register to make sure no jump happens When reading the temp.

The existing TSENS temperature read logic polls the valid bit and then
reads the temperature register. When temperature reads are triggered
at very short intervals, this can race with hardware updates and allow
the temperature field to be read while it is still being updated.
In this case, the valid bit may already be asserted even though the
temperature value is transitioning, resulting in an incorrect reading.
Hardware programming guidelines require the temperature value and the
valid bit to be sampled atomically in the same read transaction. A
reading is considered valid only if the valid bit is observed set in
that same sample.
The guidelines further specify that software should attempt the
temperature read up to three times to account for transient update
windows. If none of the attempts yields a valid sample, a stable fallback
value must be returned: if the first and second samples match, the second
value is returned;otherwise, if the second and third samples match, the
third value is returned;if neither pair matches, -EAGAIN is returned.
Update the TSENS sensor read logic to implement atomic sampling along
with the recommended retry-and-compare fallback behavior. This removes
the race window and ensures deterministic temperature values in
accordance with hardware requirements.

Add SM_THERMAL_CALIB_READ at SMC ID 0x82000047 in the command
table and implement meson_sm_get_thermal_calib(), which forwards the
tsensor_id argument to the secure monitor and returns the calibration data.
Also realign the CMD() column to improve readability.

Add the amlogic,t7-thermal compatible for the Amlogic T7 thermal sensor.
Unlike existing variants which use a phandle to the ao-secure syscon,
the T7 relies on a secure monitor interface described by a phandle and
a sensor index argument.
The T7 integrates multiple thermal sensors, all accessed through the
same SMC call. The sensor index argument is required to identify which
sensor's calibration data the secure monitor should return, as a single
SM_THERMAL_CALIB_READ command serves all of them.
Introduce the amlogic,secure-monitor property as a phandle-array and
make amlogic,ao-secure or amlogic,secure-monitor conditionally required
depending on the compatible.

Use devm_thermal_of_cooling_device_register() to simplify resource
management and avoid manual cleanup in error paths.
As a side effect this change has the benefit of solving an existing
issue. Before, the function tegra_soctherm_remove() only called
debugfs_remove_recursive() and never called thermal_cooling_device_unregister()
for any of the cooling devices registered here.
After the driver removal, the thermal framework's cdev list would
still hold references to thermal_cooling_device objects whose devdata
pointer (ts) pointed to memory already freed by the platform device's
devm cleanup.
With this change, the cooling device is unregistered when the driver
is removed, thus fixing the issue above.
