* hwmon: (pmbus) Introduce PMBUS symbol namespaceGuenter Roeck2021-04-2036-19/+54

* hwmon: (pmbus) Add pmbus driver for MAX15301Erik Rosen2021-04-203-0/+199
| | | | | | | | | | | | | | | | | | Add pmbus driver support for Maxim MAX15301 InTune Automatically Compensated Digital PoL Controller with Driver and PMBus Telemetry Even though the specification does not specifically mention it, extensive empirical testing has revealed that auto-detection of limit-registers will fail in a random fashion unless the delay parameter is set to above about 80us. The default delay is set to 100us to include some safety margin. This patch is tested on a Flex BMR461 converter module.

* hwmon: Add driver for fsp-3y PSUs and PDUsVáclav Kubernát2021-04-203-0/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for these devices: - YH-5151E - the PDU - YM-2151E - the PSU The device datasheet says that the devices support PMBus 1.2, but in my testing, a lot of the commands aren't supported and if they are, they sometimes behave strangely or inconsistently. For example, writes to the PAGE command requires using PEC, otherwise the write won't work and the page won't switch, even though, the standard says that PEC is optional. On the other hand, writes to SMBALERT don't require PEC. Because of this, the driver is mostly reverse engineered with the help of a tool called pmbus_peek written by David Brownell (and later adopted by my colleague Jan Kundrát). The device also has some sort of a timing issue when switching pages, which is explained further in the code. Because of this, the driver support is limited. It exposes only the values that have been tested to work correctly.

| | | | | | | | | | | | | | Add support for fan drawer's capability and present registers in order to set mapping between the fan drawers and tachometers. Some systems are equipped with fan drawers with one tachometer inside. Others with fan drawers with several tachometers inside.

* hwmon: add driver for NZXT Kraken X42/X52/X62/X72Jonas Malaco2021-04-203-0/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are "all-in-one" CPU liquid coolers that can be monitored and controlled through a proprietary USB HID protocol. While the models have differently sized radiators and come with varying numbers of fans, they are all indistinguishable at the software level. The driver exposes fan/pump speeds and coolant temperature through the standard hwmon sysfs interface. Fan and pump control, while supported by the devices, are not currently exposed. The firmware accepts up to 61 trip points per channel (fan/pump), but the same set of trip temperatures has to be maintained for both; with pwmX_auto_point_Y_temp attributes, users would need to maintain this invariant themselves. Instead, fan and pump control, as well as LED control (which the device also supports for 9 addressable RGB LEDs on the CPU water block) are left for existing and already mature user-space tools, which can still be used alongside the driver, thanks to hidraw. A link to one, which I also maintain, is provided in the documentation. The implementation is based on USB traffic analysis. It has been runtime tested on x86_64, both as a built-in driver and as a module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was an issue in how the tach feedbacks of dual rotor fans were reported during any change in fan speeds with revision "A" of the MAX31785. When the fan speeds would transition to a new target speed, the rotor not wired to the TACH input when TACHSEL = 0 would report a speed of 0 until the new target was reached. This has been fixed, resulting in a revision "B" update where the MFR_REVISION of "B" is 0x3061.

This simplifies error handling and is more efficient for new-style PWM hardware drivers. Instead of repeatedly querying the PWM framework about the initial PWM configuration, cache the settings in driver data. Also use __set_pwm() in .probe() to have the algorithm calculating the PWM state in a single place.
