hwmon: (sbtsi) Add basic support for SB-TSI sensors

2020-12-12T16:32:35+00:00

SB Temperature Sensor Interface (SB-TSI) is an SMBus compatible
interface that reports AMD SoC's Ttcl (normalized temperature),
and resembles a typical 8-pin remote temperature sensor's I2C interface
to BMC.

This commit adds basic support using this interface to read CPU
temperature, and read/write high/low CPU temp thresholds.

To instantiate this driver on an AMD CPU with SB-TSI
support, the i2c bus number would be the bus connected from the board
management controller (BMC) to the CPU. The i2c address is specified in
Section 6.3.1 of the spec [1]: The SB-TSI address is normally 98h for
socket 0 and 90h for socket 1, but it could vary based on hardware address
select pins.

[1]: https://www.amd.com/system/files/TechDocs/56255_OSRR.pdf

Test status: tested reading temp1_input, and reading/writing
temp1_max/min.

hwmon: (ltc2992) Add support

2020-12-11T15:42:27+00:00

LTC2992 is a rail-to-rail system monitor that
measures current, voltage, and power of two supplies.

Two ADCs simultaneously measure each supply’s current.
A third ADC monitors the input voltages and four
auxiliary external voltages.

hwmon: add Corsair PSU HID controller driver

2020-12-03T01:42:23+00:00

The Corsair digital power supplies of the series RMi, HXi and AXi include
a small micro-controller with a lot of sensors attached. The sensors can
be accessed by an USB connector from the outside.

This micro-controller provides the data by a simple proprietary USB HID
protocol. The data consist of temperatures, current and voltage levels,
power usage, uptimes, fan speed and some more. It is also possible to
configure the PSU (fan mode, mono/multi-rail, over current protection).

This driver provides access to the sensors/statistics of the RMi and HXi
series power supplies. It does not support configuring these devices,
because there would be many ways to misconfigure or even damage the PSU.

This patch adds:
- hwmon driver corsair-psu
- hwmon documentation
- updates MAINTAINERS

hwmon: Add hwmon driver for Intel MAX 10 BMC

2020-10-04T15:40:10+00:00

This patch adds hwmon functionality for Intel MAX 10 BMC chip. This BMC
chip connects to a set of sensor chips to monitor current, voltage,
thermal and power of different components on board. The BMC firmware is
responsible for sensor data sampling and recording in shared registers.
Host driver reads the sensor data from these shared registers and
exposes them to users as hwmon interfaces.
