2023-02-03hwmon: (ftsteutates) Add support for fanX_fault attributesArmin Wolf
The driver knows internally when a fan is not connected, but does not export this knowledge to userspace. Use the standard fanX_fault attributes to notify userspace if a fan is not connected.

2023-02-03hwmon: (it87) Set second Super-IO chip in configuration modeFrank Crawford
On various Gigabyte AM4 boards (AB350, AX370), the second Super-IO chip (IT8792E) needs to be in configuration mode before accessing the first due to a bug in IT8792E which otherwise results in LPC bus access errors. This needs to be done before accessing the first Super-IO chip since the second chip may have been accessed prior to loading this driver. The problem is also reported to affect IT8795E, which is used on X299 boards and has the same chip ID as IT8792E (0x8733). It also appears to affect systems with IT8790E, which is used on some Z97X-Gaming boards as well as Z87X-OC, and other more recent Gigabyte boards.

2023-02-03hwmon: (coretemp) Simplify platform device handlingRobin Murphy
Coretemp's platform driver is unconventional. All the real work is done globally by the initcall and CPU hotplug notifiers, while the "driver" effectively just wraps an allocation and the registration of the hwmon interface in a long-winded round-trip through the driver core. The whole logic of dynamically creating and destroying platform devices to bring the interfaces up and down is error prone, since it assumes platform_device_add() will synchronously bind the driver and set drvdata before it returns, thus results in a NULL dereference if drivers_autoprobe is turned off for the platform bus. Furthermore, the unusual approach of doing that from within a CPU hotplug notifier, already commented in the code that it deadlocks suspend, also causes lockdep issues for other drivers or subsystems which may want to legitimately register a CPU hotplug notifier from a platform bus notifier. All of these issues can be solved by ripping this unusual behaviour out completely, simply tying the platform devices to the lifetime of the module itself, and directly managing the hwmon interfaces from the hotplug notifiers. There is a slight user-visible change in that /sys/bus/platform/drivers/coretemp will no longer appear, and /sys/devices/platform/coretemp.n will remain present if package n is hotplugged off, but hwmon users should really only be looking for the presence of the hwmon interfaces, whose behaviour remains unchanged.

2023-01-03hwmon: (ftsteutates) Fix scaling of measurementsArmin Wolf
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. Tested on a Fujitsu DS3401-B1.

2022-12-06hwmon: (emc2305) fix pwm never being able to set lowerXingjiang Qiao
There are fields 'last_hwmon_state' and 'last_thermal_state' in the structure 'emc2305_cdev_data', which respectively store the cooling state set by the 'hwmon' and 'thermal' subsystem, and the driver author hopes that if the state set by 'hwmon' is lower than the value set by 'thermal', the driver will just save it without actually setting the pwm. Currently, the 'last_thermal_state' also be updated by 'hwmon', which will cause the cooling state to never be set to a lower value. This patch fixes that.

2022-12-04hwmon: (dell-smm) Move error message to make probing silentArmin Wolf
If dell-smm-hwmon loads on unsupported hardware like the Dell XPS 17 9710, an error message is printed. This might confuse users, as drivers are expected to be silent if no supported hardware is found. Reorder the error message so its only printed when the driver is loaded with the "force" option being set. Also reword the error message slightly. Tested on a Dell Inspiron 3505.
