2019-04-20hwmon: (max6650) add thermal cooling device capabilityJean-Francois Dagenais1-0/+1
This allows max6650 devices to be referenced in dts as a cooling device. The pwm value seems duplicated in cooling_dev_state but since pwm goes through rounding logic into data->dac, it is modified and messes with the thermal zone state algorithms. It's also better to serve a cache value, thus avoiding periodic actual i2c traffic. Signed-off-by: Jean-Francois Dagenais <jeff.dagenais@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Lochnagar is an evaluation and development board for Cirrus Logic Smart CODEC and Amp devices. It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver adds support for the hardware monitoring features of the Lochnagar 2 to the hwmon API. Monitoring is provided for the board voltages, currents and temperature supported by the board controller chip.

2018-12-22treewide: surround Kconfig file paths with double quotesMasahiro Yamada1-1/+1
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 James1-0/+2
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.

2018-05-13hwmon: (k10temp) Use API function to access System Management NetworkGuenter Roeck1-1/+1
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.
