hwmon: add driver for Aquacomputer D5 Next
This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.
Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.
Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.
The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.
This driver has been tested on x86_64, both in-kernel and as a module.

hwmon: Add Baikal-T1 PVT sensor driver
Baikal-T1 SoC provides an embedded process, voltage and temperature
sensor to monitor an internal SoC environment (chip temperature, supply
voltage and process monitor) and on time detect critical situations,
which may cause the system instability and even damages. The IP-block
is based on the Analog Bits PVT sensor, but is equipped with a
dedicated control wrapper, which provides a MMIO registers-based access
to the sensor core functionality (APB3-bus based) and exposes an
additional functions like thresholds/data ready interrupts, its status
and masks, measurements timeout. All of these is used to create a hwmon
driver being added to the kernel by this commit.
The driver implements support for the hardware monitoring capabilities
of Baikal-T1 process, voltage and temperature sensors. PVT IP-core
consists of one temperature and four voltage sensors, each of which is
implemented as a dedicated hwmon channel config.
The driver can optionally provide the hwmon alarms for each sensor the
PVT controller supports. The alarms functionality is made compile-time
configurable due to the hardware interface implementation peculiarity,
which is connected with an ability to convert data from only one sensor
at a time. Additional limitation is that the controller performs the
thresholds checking synchronously with the data conversion procedure.
Due to these limitations in order to have the hwmon alarms
automatically detected the driver code must switch from one sensor to
another, read converted data and manually check the threshold status
bits. Depending on the measurements timeout settings this design may
cause additional burden on the system performance. By default if the
alarms kernel config is disabled the data conversion is performed by
the driver on demand when read operation is requested via corresponding
_input-file.

hwmon: Driver for disk and solid state drives with temperature sensors
Reading the temperature of ATA drives has been supported for years
by userspace tools such as smarttools or hddtemp. The downside of
such tools is that they need to run with super-user privilege, that
the temperatures are not reported by standard tools such as 'sensors'
or 'libsensors', and that drive temperatures are not available for use
in the kernel's thermal subsystem.
This driver solves this problem by adding support for reading the
temperature of ATA drives from the kernel using the hwmon API and
by adding a temperature zone for each drive.
With this driver, the hard disk temperature can be read using the
unprivileged 'sensors' application:
$ sensors drivetemp-scsi-1-0
drivetemp-scsi-1-0
Adapter: SCSI adapter
temp1: +23.0°C
or directly from sysfs:
$ grep . /sys/class/hwmon/hwmon9/{name,temp1_input}
/sys/class/hwmon/hwmon9/name:drivetemp
/sys/class/hwmon/hwmon9/temp1_input:23000
If the drive supports SCT transport and reports temperature limits,
those are reported as well.
drivetemp-scsi-0-0
Adapter: SCSI adapter
temp1: +27.0°C (low = +0.0°C, high = +60.0°C)
(crit low = -41.0°C, crit = +85.0°C)
(lowest = +23.0°C, highest = +34.0°C)
The driver attempts to use SCT Command Transport to read the drive
temperature. If the SCT Command Transport feature set is not available,
or if it does not report the drive temperature, drive temperatures may
be readable through SMART attributes. Since SMART attributes are not well
defined, this method is only used as fallback mechanism.

hwmon: Add driver for fsp-3y PSUs and PDUs
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.

hwmon: add driver for NZXT Kraken X42/X52/X62/X72
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.
