hwmon: lochnagar: Add Lochnagar 2 hardware monitoring driver

2019-04-16T00:19:53+00:00

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. Signed-off-by: Lucas Tanure Signed-off-by: Charles Keepax Signed-off-by: Guenter Roeck

hwmon: Add On-Chip Controller (OCC) hwmon driver

2018-12-16T23:13:05+00:00

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. Signed-off-by: Eddie James [groeck: Fix up SPDX license identifier] Signed-off-by: Guenter Roeck

hwmon: Add support for RPi voltage sensor

2018-07-09T17:47:27+00:00

Currently there is no easy way to detect undervoltage conditions on a remote Raspberry Pi. This hwmon driver retrieves the state of the undervoltage sensor via mailbox interface. The handling based on Noralf's modifications to the downstream firmware driver. In case of an undervoltage condition only an entry is written to the kernel log.

hwmon: Add NPCM7xx PWM and Fan driver

2018-07-09T03:08:13+00:00

Add Nuvoton BMC NPCM750/730/715/705 Pulse Width Modulation (PWM) and Fan tacho driver. The Nuvoton BMC NPCM750/730/715/705 supports 8 PWM controller outputs and 16 Fan controller inputs. The driver provides a sysfs entries through which the user can configure the duty-cycle value from 0(off) and 255(full speed) and read the fan tacho rpm value.

hwmon: (mlxreg-fan) Add support for Mellanox FAN driver

2018-07-09T03:08:13+00:00

Driver obtains PWM and tachometers registers location according to the system configuration and creates FAN/PWM hwmon objects and a cooling device. PWM and tachometers are controlled through the on-board programmable device, which exports its register map. This device could be attached to any bus type, for which register mapping is supported. 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. Currently driver will be activated from the Mellanox platform driver: drivers/platform/x86/mlx-platform.c. For the future ARM based systems it could be activated from the ARM platform module.

hwmon: add support for sensors exported via ARM SCMI

2018-02-28T16:37:57+00:00

Create a driver to add support for SoC sensors exported by the System Control Processor (SCP) via the System Control and Management Interface (SCMI). The supported sensor types is one of voltage, temperature, current, and power. The sensor labels and values provided by the SCP are exported via the hwmon sysfs interface.
