* 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.

* hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow NextAleksa Savic2022-09-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | 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].

* hwmon: (max31790) add fanN_enableJustin Ledford2022-09-191-0/+1
| | | | | | | | | | | | | | 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.

* hwmon: (asus_wmi_ec_sensors) remove driverEugene Shalygin2022-09-192-39/+0
| | | | | | | | | | | | | 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>

For simplicity, the access method implemented for MAX6695/6696 is used. The chips support PEC (packet error checking). Set the PEC feature flag and let the user decide if it should be enabled or not (it is by default disabled). Even though it is only documented for ADT7483, all three chips support a secondary manufacturer ID register at 0x3e and a chip ID register at 0x3f. Use the contents of those registers register for improved chip detection accuracy. Add the same check to the ADT7461A detection code since this chip also supports the same (undocumented) registers.

Separate support for the two sets of chips to be able to support maximum temperature ranges correctly for all chips. Introduce new feature flag to indicate temperature support up to 255 degrees C. Since the chips are almost identical except for the supported temperature range, automatic chip detection is limited. Effectively this means that MAX6648 may be mis-detected as MAX6649 when auto-detected, but there is nothing we can do about that.

* | hwmon: (pmbus) Move pec attribute to I2C deviceGuenter Roeck2022-07-131-0/+9
|/ | | | | | | | | | | Enabling and disabling PEC for PMBus devices is currently only supported with a debugfs attribute, which requires debugfs to be enabled and is thus less than perfect. Take the lm90 driver as example and add a 'pec' attribute to the I2C device if both the I2C adapter and the PMBus device support it. Remove the now obsolete 'pec' attribute from debugfs.

* hwmon: Make chip parameter for with_info API mandatoryGuenter Roeck2022-05-221-1/+1
| | | | | | | | | | Various attempts were made recently to "convert" the old hwmon_device_register() API to devm_hwmon_device_register_with_info() by just changing the function name without actually converting the driver. Prevent this from happening by making the 'chip' parameter of devm_hwmon_device_register_with_info() mandatory. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

| | | | | | | | | | | | | | Add support for the temperatur sensor and the fan controller on the Microchip LAN966x SoC. Apparently, an Analog Bits PVT sensor is used which can measure temperature and process voltages. But only a forumlae for the temperature sensor is known. Additionally, the SoC support a fan tacho input as well as a PWM signal to control the fan.
