2019-11-21hwmon: Add driver for Texas Instruments TMP512/513 sensor chips.Eric Tremblay
TI's TMP512/513 are I2C/SMBus system monitor chips. These chips monitor the supply voltage, supply current, power consumption and provide one local and up to three (TMP513) remote temperature sensors.

The ltc2947 is a high precision power and energy monitor with an internal sense resistor supporting up to +/- 30A. Three internal no Latency ADCs ensure accurate measurement of voltage and current, while high-bandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.

I have been using SENSORS_W83795_FANCTRL for several years and never had any problem. When the driver was added, I had not tested that part of the driver yet so I wanted to be super cautious, but time has shown that it works just fine. In the long run I even believe that we should drop the option and enable the feature unconditionally. It doesn't do anything until the user explicitly starts twiddling with sysfs attributes anyway.

2018-12-22treewide: surround Kconfig file paths with double quotesMasahiro Yamada
The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

2018-12-16hwmon: Add On-Chip Controller (OCC) hwmon driverEddie James
The OCC is a device embedded on a POWER processor that collects and aggregates sensor data from the processor and system. The OCC can provide the raw sensor data as well as perform thermal and power management on the system. This driver provides a hwmon interface to the OCC from a service processor (e.g. a BMC). The driver supports both POWER8 and POWER9 OCCs. Communications with the POWER8 OCC are established over standard I2C bus. The driver communicates with the POWER9 OCC through the FSI-based OCC driver, which handles the lower-level communication details. This patch lays out the structure of the OCC hwmon driver. There are two platform drivers, one each for P8 and P9 OCCs. These are probed through the I2C tree and the FSI-based OCC driver, respectively. The patch also defines the first common structures and methods between the two OCC versions.

The SMN (System Management Network) on Family 17h AMD CPUs is also accessed from other drivers, specifically EDAC. Accessing it directly is racy. On top of that, accessing the SMN through root bridge 00:00 is wrong on multi-die CPUs and may result in reading the temperature from the wrong die. Use available API functions to fix the problem. For this to work, add dependency on AMD_NB. Also change the Raven Ridge PCI device ID to point to Data Fabric Function 3, since this ID is used by the API functions to find the CPU node.

The driver provides a sysfs entries through which the user can configure the duty-cycle value (ranging from 0 to 100 percent) and read the fan tach rpm value.
