The AUXADC thermal v1 allows reading temperature range between -20°C to
150°C and any value out of this range is invalid.

Add new definitions for MT8173_TEMP_{MIN_MAX} and a new small helper
mtk_thermal_temp_is_valid() to check if new readings are in range: if
not, we tell to the API that the reading is invalid by returning
THERMAL_TEMP_INVALID.

It was chosen to introduce the helper function because, even though this
temperature range is realistically ok for all, it comes from a downstream
kernel driver for version 1, but here we also support v2 and v3 which may
may have wider constraints.

Some more testing revealed that this commit introduces a regression on some
MT8173 Chromebooks and at least on one MT6795 Sony Xperia M5 smartphone due
to the delay being apparently variable and machine specific.

Another solution would be to delay for a bit more (~70ms) but this is not
feasible for two reasons: first of all, we're adding an even bigger delay
in a probe function; second, some machines need less, some may need even
more, making the msleep at probe solution highly suboptimal.

This reverts commit 10debf8c.

Some older processors don't allow BIT(13) and BIT(15) in the current
mask set by "THERM_STATUS_CLEAR_CORE_MASK". This results in:

unchecked MSR access error: WRMSR to 0x19c (tried to
write 0x000000000000aaa8) at rIP: 0xffffffff816f66a6
(throttle_active_work+0xa6/0x1d0)

To avoid unchecked MSR issues, check CPUID for each relevant feature and
use that information to set the supported feature bits only in the
"clear" mask for cores. Do the same for the analogous package mask set
by "THERM_STATUS_CLEAR_PKG_MASK".

Introduce functions thermal_intr_init_core_clear_mask() and
thermal_intr_init_pkg_clear_mask() to set core and package mask bits,
respectively. These functions are called during initialization.

 "Several fixes for driver startup regressions that landed during the
  merge window as well as some older bugs.

  The regressions were due to a lack of testing with what the CXL
  specification calls Restricted CXL Host (RCH) topologies compared to
  the testing with Virtual Host (VH) CXL topologies. A VH topology is
  typical PCIe while RCH topologies map CXL endpoints as Root Complex
  Integrated endpoints. The impact is some driver crashes on startup.

  This merge window also added compatibility for range registers (the
  mechanism that CXL 1.1 defined for mapping memory) to treat them like
  HDM decoders (the mechanism that CXL 2.0 defined for mapping
  Host-managed Device Memory). That work collided with the new region
  enumeration code that was tested with CXL 2.0 setups, and fails with
  crashes at startup.

  Lastly, the DOE (Data Object Exchange) implementation for retrieving
  an ACPI-like data table from CXL devices is being reworked for v6.4.
  Several fixes fell out of that work that are suitable for v6.3.

  All of this has been in linux-next for a while, and all reported
  issues [1] have been addressed.

  Summary:

   - Fix several issues with region enumeration in RCH topologies that
     can trigger crashes on driver startup or shutdown.

   - Fix CXL DVSEC range register compatibility versus region
     enumeration that leads to startup crashes

   - Fix CDAT endiannes handling

   - Fix multiple buffer handling boundary conditions

   - Fix Data Object Exchange (DOE) workqueue usage vs
     CONFIG_DEBUG_OBJECTS warn splats"

The caller of the function thermal_zone_device_register_with_trips()
can pass a thermal_zone_params structure parameter.

This one is used by the thermal core code until the thermal zone is
destroyed. That forces the caller, so the driver, to keep the pointer
valid until it unregisters the thermal zone if we want to make the
thermal zone device structure private the core code.

As the thermal zone device structure would be private, the driver can
not access to thermal zone device structure to retrieve the tzp field
after it passed it to register the thermal zone.

So instead of forcing the users of the function to deal with the tzp
structure life cycle, make the usage easier by allocating our own
thermal zone params, copying the parameter content and by freeing at
unregister time. The user can then create the parameters on the stack,
pass it to the registering function and forget about it.

The driver is using the devm_thermal_of_zone_device_register().

In the error path of the function calling
devm_thermal_of_zone_device_register(), the function
devm_thermal_of_zone_unregister() should be called instead of
thermal_of_zone_unregister(), otherwise this one will be called twice
when the device is freed.

The same happens for the remove function where the devm_ guarantee the
thermal_of_zone_unregister() will be called, so adding this call in
the remove function will lead to a double free also.

Use devm_ variant in the error path of the probe function.

Remove thermal_of_zone_unregister() in the remove function.

The binary representation for sensor 1 interrupt status was incorrectly
assembled, when compared to the full table given in the same comment
section. The conversion into hex was also incorrect, leading to
incorrect interrupt status bitmask for sensor 1. This would cause the
driver to incorrectly identify changes for sensor 1, when in fact it
was sensor 0, or a sensor access time out.

Fix the binary and hex representations in the comments, and the actual
bitmask macro.

Commit 32a7a021 ("thermal/core: Relocate the traces definition in
thermal directory") moves include/trace/events/thermal_power_allocator.h to
drivers/thermal/thermal_trace_ipa.h, but misses to adjust the file
entry for the THERMAL/POWER_ALLOCATOR section.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Adjust this file entry in THERMAL/POWER_ALLOCATOR.

Thermal zones located in power domains may not be accessible when
the domain is powergated. In this situation, reading the temperature
will return -BPMP_EFAULT. When evaluating trips, BPMP will internally
use -256C as the temperature for offline zones.

For smooth operation, for offline zones, return -EAGAIN when reading
the temperature and allow registration of zones even if they are
offline during probe.
