On some pre-production hardware, the SoCs do not contain calibration
data for the thermal sensors. The downstream drivers provide default
values that sort of work, instead of having the thermal sensors not
work at all.

Port the default values to the upstream driver. These values are from
the ChromeOS kernels, which sadly do not cover the MT7988.

Linux kernel uses thermal zone node name during registering thermal

NUL byte.  The bindings expect node names to finish with '-thermal'

As a result, the change is made in the dt-bindings and in the LVTS

This add suspend-to-ram support.

The derived_table is kept-as is, so the resume is only about
pm_runtime_* calls and restoring the same registers as the probe.

Extract the hardware initialization procedure to a function called at
both probe-time & resume-time.

The probe-time loop is split in two to ensure doing the hardware
initialization before registering thermal zones. That ensures our
callbacks cannot be called while in bad state.

The 100ms delay in the hardware initialization sequence was removed.
It was initially added to be sure the thresholds are programmed before
enabling the interrupt, but in fact it's not needed (tested on J7200
platform).

The order in which lists are sorted in __thermal_zone_device_update()
is reverse with respect to what it should be due to a mistake in
thermal_trip_notify_cmp().

Fix it and observe that it is not necessary to sort the lists in
different orders.  They can both be sorted in ascending order if
way_down_list is walked in reverse order which allows the code to
be slightly more straightforward (and less prone to silly mistakes).

Commit 202aa0d4 ("thermal: core: Do not call handle_thermal_trip()
if zone temperature is invalid") caused __thermal_zone_device_update()
to return early if the current thermal zone temperature was invalid.

This was done to avoid running handle_thermal_trip() and governor
callbacks in that case which led to confusion.  However, it went too
far because monitor_thermal_zone() still needs to be called even when
the zone temperature is invalid to ensure that it will be updated
eventually in case thermal polling is enabled and the driver has no
other means to notify the core of zone temperature changes (for example,
it does not register an interrupt handler or ACPI notifier).

Also if the .set_trips() zone callback is expected to set up monitoring
interrupts for a thermal zone, it has to be provided with valid
boundaries and that can only happen if the zone temperature is known.

Accordingly, to ensure that __thermal_zone_device_update() will
run again after a failing zone temperature check, make it call
monitor_thermal_zone() regardless of whether or not the zone
temperature is valid and make the latter schedule a thermal zone
temperature update if the zone temperature is invalid even if
polling is not enabled for the thermal zone.

Pull ata fixes from Niklas Cassel:

   Considering that we now have had bug reports for 3 different BX SSD1
   variants from Crucial with the same product name, make the quirk more
   inclusive, to catch more device models from the same generation.

 - Fix a trivial NULL pointer dereference in the error path for
   ata_host_release().

 - Create a ata_port_free(), so that we don't miss freeing ata_port
   struct members when freeing a struct ata_port.

 - Fix a trivial double free in the error path for ata_host_alloc().

 - Ensure that we remove the libata "remapped NVMe device count" sysfs
   entry on .probe() error.

.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however,
if probe() fails after this call, we currently never call
sysfs_remove_file_from_group().

(The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one())
does not help, as .remove() is not called on .probe() error.)

Thus, if probe() fails after the sysfs_add_file_to_group() call, the next
time we insmod the module we will get:

The kernel test robot reported that clang no longer compiles the 32-bit
x86 kernel in some configurations due to commit 95ece481
("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}()
functions").

The build fails with

  arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available

and the reason seems to be that not only does the cmpxchg8b instruction
need four fixed registers (EDX:EAX and ECX:EBX), with the emulation
fallback the inline asm also wants a fifth fixed register for the
address (it uses %esi for that, but that's just a software convention
with cmpxchg8b_emu).

Avoiding using another pointer input to the asm (and just forcing it to
use the "0(%esi)" addressing that we end up requiring for the sw
fallback) seems to fix the issue.
