Switch to devm_thermal_of_cooling_device_register to simplify the

When load this mode, we can see the following log:
"power_meter ACPI000D:00: hwmon_device_register() is deprecated. Please
convert the driver to use hwmon_device_register_with_info()."
So replace hwmon_device_register with hwmon_device_register_with_info.
These attributes, 'power_accuracy', 'power_cap_hyst', 'power_average_min'
and 'power_average_max', should have been placed in hwmon_chip_info as
power data type. But these attributes are displayed as string format on
the following case:
a) power1_accuracy --> display like '90.0%'
b) power1_cap_hyst --> display 'unknown' when its value is 0xFFFFFFFF
c) power1_average_min/max --> display 'unknown' when its value is
negative.
To avoid any changes in the display of these sysfs interfaces, we can't
modifiy the type of these attributes in hwmon core and have to put them
to extra_groups.
Please note that the path of these sysfs interfaces are modified
accordingly if use hwmon_device_register_with_info():
old: all sysfs interfaces are under acpi device, namely,
/sys/class/hwmon/hwmonX/device/
now: all sysfs interfaces are under hwmon device, namely,
/sys/class/hwmon/hwmonX/
The new ABI does not guarantee that the underlying path remains the same.
But we have to accept this change so as to replace the deprecated API.
Fortunately, some userspace application, like libsensors, would scan
the two path and handles this automatically. So we can accept this change
so as to drop the deprecated message.

Add support for the Congatec Board Controller. This controller exposes
temperature, voltage, current and fan sensors.
The available sensors list cannot be predicted. Some sensors can be

boards. The Board Controller gives to the driver its sensors list, and
their status (active or not).

Add support for LT7170 and LT7171. The LT7170 and LT7171 are 20 A, 16 V,
Single- or Dual-Phase, Silent Switcher Step-Down Regulators with Digital
Power System Management.
The relevant registers in the LT7170 and LT7171 are similar to those in
the LTC3887, but with fewer channels. This adds the chip ID and
identification of ASCII to differentiate between the LT7170 and LT7171.
These devices support polling for status updates and clearing peak
values. The data format for voltage, current, and temperature is set to
IEEE754 for precision and compatibility.

When the ntc is reading Out Of Bounds instead of clipping to the nearest
limit (min/max) return -ENODATA. This prevents malfunctioning sensors
from sending a device into a shutdown loop due to a critical trip.
This implementation will only work for ntc type thermistors if a ptc
type is to be implemented the min/max ohm calculation must be adjusted
to take that into account.

We encountered a problem that a fake power alarm is reported to
user on the platform unsupported notifications at the second step
below:
1> Query 'power1_alarm' attribute when the power capping occurs.
2> Query 'power1_alarm' attribute when the power capping is over
and the current average power is less then power cap value.
The root cause is that the resource->power_alarm is set to true
at the first step. And power meter use this old value to show
the power alarm state instead of the current the comparison value.

Define debugfs attributes which need block data access in a data
structure and loop through it instead of creating debugfs files
one by one. This reduces code size and simplifies adding additional
attributes if needed.
While this is currently only used for manufacturer specific attributes,
the access code is generic and also works for other block attributes,
so rename operation functions from _mfg to _block.
While at it, rename the "revison" file to "pmbus_revision" to make its
meaning more obvious and to create a clear distinction against the
"mfg_revision" file.

The `pmbus_identify()` function fails to correctly determine the number
of supported pages on PMBus devices. This occurs because `info->pages`
is implicitly zero-initialised, and `pmbus_set_page()` does not perform
writes to the page register if `info->pages` is not yet initialised.
Without this patch, `info->pages` is always set to the maximum after
scanning.
This patch initialises `info->pages` to `PMBUS_PAGES` before the probing
loop, enabling `pmbus_set_page()` writes to make it out onto the bus
correctly identifying the number of pages. `PMBUS_PAGES` seemed like a
reasonable non-zero number because that's the current result of the
identification process.
Testing was done with a PMBus device in QEMU.

When an Icelake or Sapphire Rapids CPU isn't providing the maximum and
critical thresholds for particular DIMM the driver should return an
error to the userspace instead of giving it stale (best case) or wrong
(the structure contains all zeros after kzalloc() call) data.
The issue can be reproduced by binding the peci driver while the host is
fully booted and idle, this makes PECI interaction unreliable enough.

evaluated using 32-bit arithmetic.
Since a value of type 'u64' is used to store the eventual result,
and this result is later sent to the function usecs_to_jiffies with

NCT7716 is similar to NCT7717 but has one more address support,
both of them only have a 8 bit resolution local thermal sensor.
NCT7718 has 11 bit resoulution remote thermal sensor.

Add support for LTM4673. The LTM4673 is a quad output, dual 12A and dual
5A, switching mode DC/DC step-down μModule regulator integrated with
4-channel power system manager.
This adds only the chip id, the checks for the manufacturer special id,
and the relevant attributes for the device's pmbus_driver_info.
The device does not support clear peaks.

REGCACHE_NONE is the default type of the cache when not provided.
Drop unneeded explicit assignment to it.
Note, it's defined to 0, and if ever be redefined, it will break
literally a lot of the drivers, so it very unlikely to happen.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and debugfs updates from Greg KH:
"Here is the big set of driver core and debugfs updates for 6.14-rc1.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at
least one user that does have a regression with these, but Al is
working on tracking down the fix for it. In my use (and everyone
else's linux-next use), it does not seem like a big issue at the
moment.
Here's a short list of the things in here:
- driver core rust bindings for PCI, platform, OF, and some i/o
functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing
things in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon""

- Improve initialization of numbered I2C adapters
Drivers:
- use parity8 helper
- dw: fix possible use-after-free
- mipi-i3c-hci: add support for PCI bus host
- svc: many fixes for IBI and hotjoin"
