Add support for medium repeatability. Per datasheet: The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurements at the stated repeatability and at constant ambient conditions. It is a measure for the noise on the physical sensor output. Different measurement modes allow for high/medium/low repeatability. For the humidity sensor, repeatability is documented as 0.25% RH for low repeatability, 0.15% RH for medium repeatability, and 0.10% RH for high repeatability. Support all three modes. Signed-off-by:

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. Signed-off-by:

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. Link to the comment above debugfs_create_dir: https://elixir.bootlin.com/linux/latest/source/fs/debugfs/inode.c#L565Signed-off-by:

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).

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.

Commit 848ba0a2 ("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. Signed-off-by:

beep_enable, inX_beep, currX_beep, fanX_beep, and tempX_beep are standard attributes mentioned in the sysfs interface specification but not implemented in the hwmon core. Since these are not deprecated, implement them. Adding beep_mask is not necessary, as it is deprecated and the drivers already using it are manually defining it. Signed-off-by:

The PMON_CONFIG register on ADM1272 is a 16 bit register. Writing a 8 bit value into it clears the upper 8 bits of the register, resulting in unexpected side effects. Fix by writing the 16 bit register value. Also, it has been reported that temperature readings are sometimes widely inaccurate, to the point where readings may result in device shutdown due to errant overtemperature faults. Improve by enabling temperature sampling. While at it, move the common code for ADM1272 and ADM1278 into a separate function, and clarify in the error message that an attempt was made to enable both VOUT and temperature monitoring. Last but not least, return the error code reported by the underlying I2C controller and not -ENODEV if updating the PMON_CONFIG register fails. After all, this does not indicate that the chip is not present, but an error in the communication with the chip.
