* 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.

* | hwmon: (ftsteutates) Fix scaling of measurementsArmin Wolf2023-01-031-0/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | A user complained that the ftsteutates driver was displaying bogus values since its introduction. This happens because the sensor measurements need to be scaled in order to produce meaningful results: - the fan speed needs to be multiplied by 60 since its in RPS - the temperature is in degrees celsius and needs an offset of 64 - the voltage is in 1/256 of 3.3V The offical datasheet says the voltage needs to be divided by 256, but this is likely an off-by-one-error, since even the BIOS devides by 255 (otherwise 3.3V could not be measured). The voltage channels additionally need a board-specific multiplier, however this can be done by the driver since its board-specific. The reason the missing scaling of measurements is the way Fujitsu used this driver when it was still out-of-tree. Back then, all scaling was done in userspace by libsensors, even the generic one.

As far as I could gather all OXP boards have the same DMI strings and they can be told appart only by the boot cpu vendor (Intel/AMD). Currently only AMD boards are supported since Intel have different EC registers and values to read/write. Fan control is provided via pwm interface in the range [0-255]. AMD boards have [0-100] as range in the EC, the written value is scaled to accommodate for that.

* hwmon: (pwm-fan) Switch regulator dynamicallyAlexander Stein2022-09-251-0/+12
| | | | | | | | | | | | | | | | | | This adds the enable attribute which is used to select if zero PWM duty means to switch off regulator and PWM or to keep them enabled but at inactive PWM output level. Depending on the select enable mode, turn off the regulator and PWM if the PWM duty is zero, or keep them enabled. This is especially important for fan using inverted PWM signal polarity. Having regulator supplied and PWM disabled, some PWM controllers provide the active, rather than inactive signal. With this change the shutdown as well as suspend/resume paths require modifcations as well.

| | | | | | | | | | | | | | | | | | | | | | | Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer High Flow Next flow sensor, which communicates through a proprietary USB HID protocol. The High Flow Next exposes +5V voltages, water quality, conductivity and flow readings. A temperature sensor can be connected to it, in which case it provides its reading and an estimation of the dissipated/absorbed power in the liquid cooling loop. Additionally, serial number and firmware version are exposed through debugfs. Registry offsets were discovered and tested by users on Github [1] [2].

| | | | | | | | | | | | | | The MAX31790 has a tach input enable bit in each fan's configuration register. This is only enabled by the driver if RPM mode is selected, but the driver doesn't provide a way to independently enable tachometer input regardless of the regulator mode. By adding the fanN_enable sysfs files, we can decouple the tach input from the regulator mode. Also update the documentation.

| | | | | | | | | | | | | This driver utilises a WMI interface found in AMD 500 series ASUS boards, to read EC registers. But it turned out that ASUS abandoned the interface, as it disappeared from Intel 600 series boards. Additionally, the WMI interface was incredibly slow. Therefore this driver was deprecated in favor of the asus_ec_sensors driver, which supports more boards, more sensors, and is faster.

Maybe, six years ago, we were not ready but let us remove old content for the better now and structure and maintain less content in the kernel documentation with a better result. Drop this already outdated document and adjust all textual references. Here is an argument why deleting the content will not remove any useful information to the existing kernel documentation, individually broken down for each section. Section "Allocating Device Numbers" refers to https://www.lanana.org/, and then refers to Documentation/admin-guide/devices.rst. However, the devices.rst clearly states: "The version of this document at lanana.org is no longer maintained." Everything needed for submitting drivers is already stated in devices.rst and the reference to https://www.lanana.org/ is outdated, and should be just deleted. Section "Who To Submit Drivers To" is all about Linux 2.0 - 2.6, before the new release version scheme; the mentioned developers are still around, but actually not the first developers to contact anymore. Section "What Criteria Determine Acceptance" has a few bullet points: Licensing and Copyright is well-covered in process/kernel-license.rst. Interfaces, Code, Portability, Clarity state some obvious things about ensuring kernel code quality. Control suggests to add a MAINTAINERS entry, which is already mentioned in 6.Followthrough.rst: "... added yourself to the MAINTAINERS file..." PM support states a bit about implementing and testing power management of a driver, it remains an open question where to place that in the process documents. Driver developers interested in power management will find the corresponding part on power management in the kernel documentation anyway. In section "What Criteria Do Not Determine Acceptance", the points Vendor and Author states something basic consequence of the kernel being an open-source community software development. Probably no need to mention it nowadays. Section "Resources" lists resources that are also mentioned elsewhere more central. - Linux kernel tree and mailing list is mentioned in many places. - https://lwn.net/Kernel/LDD3/ is mentioned in Documentation/process/kernel-docs.rst. - https://lwn.net/ is mentioned in: - Documentation/process/8.Conclusion.rst - Documentation/process/kernel-docs.rst - https://kernelnewbies.org/ is mentioned in: - Documentation/process/8.Conclusion.rst - Documentation/process/kernel-docs.rst - http://www.linux-usb.org/ is mentioned in Documentation/driver-api/usb/usb.rst - https://landley.net/kdocs/ols/2002/ols2002-pages-545-555.pdf is mentioned in Documentation/process/kernel-docs.rst - https://kernelnewbies.org/KernelJanitors is mentioned in Documentation/process/howto.rst - https://git-scm.com/ is mentioned in - Documentation/process/2.Process.rst - Documentation/process/7.AdvancedTopics.rst - Documentation/process/howto.rst Signed-off-by: Lukas Bulwahn <lukas.bulwahn@gmail.com> Link: https://lore.kernel.org/r/20220704122537.3407-7-lukas.bulwahn@gmail.com Signed-off-by: Jonathan Corbet <corbet@lwn.net>
