* hwmon: (max31827) Add custom attribute for resolutionDaniel Matyas2023-12-111-6/+23
| | | | | | | | | | | | | | | | | | | Added custom channel-specific (temp1) attribute for resolution. The wait time for a conversion in one-shot mode (enable = 0) depends on the resolution. When resolution is 12-bit, the conversion time is 140ms, but the minimum update_interval is 125ms. Handled this problem by waiting an additional 15ms (125ms + 15ms = 140ms). Added 'mask' parameter to the shutdown_write() function. Now it can either write or update bits, depending on the value of mask. This is needed, because for alarms a write is necessary, but for resolution only the resolution bits should be updated.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: add HP WMI Sensors driverJames Seo2023-06-082-0/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* hwmon: (aquacomputer_d5next) Add support for Aquacomputer Aquastream XTAleksa Savic2023-04-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer Aquastream XT watercooling pump, which communicates through a proprietary USB HID protocol. Implemented by Leonard Anderweit [1] [2]. Coolant temp, fan IC and external temp sensor readings are available, along with speed and voltage of both the pump and optionally connected fan. It also exposes pump current. Additionally, serial number and firmware version are exposed through debugfs.

* hwmon: (aquacomputer_d5next) Add fan PWM control for AquaeroLeonard Anderweit2023-04-191-1/+2
| | | | | | | | | | | | | | Add the option to control fan PWM on Aquacomputer Aquaero. The Aquaero is the most complex Aquacomputer device, control is therefore more complicated then on already supported devices. Setting PWM requires multiple steps. First, an internal static PWM controller is set to the desired PWM value. Second, the fan is set to use that PWM controller. Last, the minimum and maximum accepted PWM values of the fan are set to allow all possible PWM values.

| | | | | | | | | | | | | | | | | | | | | | | | Even though the hardware monitoring documentation already stated that new drivers should use [devm_]devm_hwmon_device_register_with_info() to register with the hardware monitoring subsystem, we still get submissions for new drivers using the older APIs. There is no benefit to use those APIs. On the contrary, using the older APIs results in substantially larger code size. Explicitly deprecate [devm_]hwmon_device_register_with_groups() to ensure that all new drivers use the latest API. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
