2023-07-27hwmon: (k10temp) Enable AMD3255 Proc to show negative temperatureBaskaran Kannan
Industrial processor i3255 supports temperatures -40 deg celcius to 105 deg Celcius. The current implementation of k10temp_read_temp rounds off any negative temperatures to '0'. To fix this, the following changes have been made. A flag 'disp_negative' is added to struct k10temp_data to support AMD i3255 processors. Flag 'disp_negative' is set if 3255 processor is found during k10temp_probe. Flag 'disp_negative' is used to determine whether to round off negative temperatures to '0' in k10temp_read_temp.

2023-07-26hwmon: (pmbus_core) Fix Deadlock in pmbus_regulator_get_statusGuenter Roeck
pmbus_regulator_get_status() acquires update_lock. pmbus_regulator_get_error_flags() acquires it again, resulting in an immediate deadlock.

2023-07-18hwmon: (oxp-sensors) Move tt_toggle attribute to dev_groupsJoaquín Ignacio Aramendía
A driver should not be manually adding groups in its probe function (it will race with userspace), so replace the call to devm_device_add_groups() to use the platform dev_groups callback instead.

2023-06-17hwmon: (oxp-sensors) Add tt_toggle attribute on supported boardsJoaquín Ignacio Aramendía
OneXPlayer boards from the last generation (both for OneXPlayer and AOK ZOE brands) have a toggle in the EC to switch the "Turbo/Silent" button into a different keyboard event. Add a means to use that "Turbo button takeover" function and expose it to userspace in a custom sysfs `tt_toggle` attribute. It can be read to take the current state. Write 1|0 to activate the function. The specific keycode is dependent on the board but can be checked by running `evtest` utility. Newer BIOS on the OneXPlayer added this function aside from string changes. Add a board enum to differentiate it from the old OneXplayer Mini AMD BIOS.

2023-06-10hwmon: (lm75) Use maple tree register cacheMark Brown
The lm75 is only capable of performing single register read and write operations which means it gains no advantage from using a rbtree register cache, convert it to using the more modern maple tree register cache instead. This should be more efficient.

2023-06-08hwmon: (it87) Generalise support for FAN_CTL ON/OFFFrank Crawford
Support for FAN_CTL ON/OFF is currently disabled only for IT8603E but there are severl chips that don't support the configuration bits to turn off fan control entirely. Generalise this support for any chip. Add feature flag FEAT_FANCTL_ONOFF for chips that support configuration bits for management of fan control off and assign all chips that support the configuration.

2023-06-08hwmon: (pmbus/adm1266) Drop unnecessary error check for debugfs_create_dirOsama Muhammad
This patch removes the error checking for debugfs_create_dir in adm1266.c. This is because the debugfs_create_dir() does not return NULL but an ERR_PTR after an error. The DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes.The debugfs Api handles it gracefully. The check is unnecessary.

2023-06-08hwmon: add HP WMI Sensors driverJames Seo
Hewlett-Packard (and some HP Compaq) business-class computers report hardware monitoring information via WMI. This driver exposes that information to hwmon. Initial support is provided for temperature, fan speed, and intrusion sensor types. Provisional support is provided for voltage and current sensor types. HP's WMI implementation permits many other types of numeric sensors. Therefore, a debugfs interface is also provided to enumerate and inspect all numeric sensors visible on the WMI side. This should facilitate adding support for other sensor types in the future. Tested on a HP Z420, a HP EliteOne 800 G1, and a HP Compaq Elite 8300 SFF. Note that provisionally supported sensor types are untested and seem to be rare-to-nonexistent in the wild, having been encountered neither on test systems nor in ACPI dumps from the Linux Hardware Database. They are included because their popularity in general makes their presence on past or future HP systems plausible and because no doubt exists as to how the sensors themselves would be represented in WMI (alarm attributes will need to wait for hardware to be located). A 2005 HP whitepaper gives the relevant sensor object MOF definition and sensor value scaling calculation, and both this driver and the official HP Performance Advisor utility comply with them (confirmed in the latter case by reverse engineering).

MAX31827 is a low-power temperature switch with I2C interface. The device is a ±1°C accuracy from -40°C to +125°C (12 bits) local temperature switch and sensor with I2C/SM- Bus interface.

Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer Leakshield leak prevention system, which communicates through a proprietary USB HID protocol. Implemented by Noah Bergbauer [1]. Two temperature sensors are exposed, along with pressure (current, min, max and target), reservoir volume (total and filled), pump speed and flow. Pump speed and flow values are user provided and allow the Leakshield to optimize its operation. Writing them to the device is subject of future patches.

2023-06-08hwmon: (core) Finish renaming groups parameter in API to extra_groupsJames Seo
Commit 848ba0a2f20d ("hwmon: (core) Rename groups parameter in API to extra_groups") renames the 'groups' parameter of devm_hwmon_device_register_with_info() to 'extra_groups' in hwmon-kernel-api.txt (later .rst) and hwmon.h, but this change was not propagated to the function code itself in hwmon.c. Finish the job. Note that hwmon_device_register_with_info() has the same parameter, and the name of that parameter was changed in all three files. Harmonizing the name between these related functions also removes a potential source of confusion.
