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.

This allows max6650 devices to be referenced in dts as a cooling device.

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.

Single instance is created with one PWM control, up to 12 tachometers and one cooling device. It could be as many instances as programmable device supports.

2018-05-13hwmon: (k10temp) Use API function to access System Management NetworkGuenter Roeck
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.

2016-07-12hwmon: (tmp102) Convert to use regmap, and drop local cacheGuenter Roeck
By converting the driver to regmap, we can use regmap to cache non-volatile registers. Stop caching the temperature register; while potentially reading it more often can result in reading it more often than necessary, this is offset by the gain due to not re-reading the limit registers. A positive side effect of this change is that limit registers can now be read and updated before the first temperature conversion is complete.
