hwmon: (nct6775) Add i2c driver

2022-05-22T18:32:31Z

This driver provides an i2c I/O mechanism for the core nct6775 driver, as might be used by a BMC. Because the Super I/O chip is shared with the host CPU in such a scenario (and the host should ultimately be in control of it), the i2c driver is strictly read-only to avoid interfering with any usage by the host (aside from the bank-select register, which seems to be replicated for the i2c interface).

hwmon: add driver for the Microchip LAN966x SoC

2022-05-22T18:32:30Z

Add support for the temperatur sensor and the fan controller on the Microchip LAN966x SoC. Apparently, an Analog Bits PVT sensor is used which can measure temperature and process voltages. But only a forumlae for the temperature sensor is known. Additionally, the SoC support a fan tacho input as well as a PWM signal to control the fan.

hwmon: (nct6775) Split core and platform driver

2022-05-20T17:57:06Z

This splits the nct6775 driver into an interface-independent core and a separate platform driver that wraps inb/outb port I/O (or asuswmi methods) around that core.

hwmon: (aquacomputer_d5next) Add support for Aquacomputer Farbwerk

2022-05-20T17:57:05Z

Extend aquacomputer_d5next driver to expose hardware temperature sensors of the Aquacomputer Farbwerk RGB controller, which communicates through a proprietary USB HID protocol. Four temperature sensors are available. Additionally, serial number and firmware version are exposed through debugfs. Also, add Jack Doan to MAINTAINERS for this driver.

hwmon: (dell-smm) Add cooling device support

2022-05-17T12:53:00Z

Until now, only the temperature sensors where exported thru the thermal subsystem. Export the fans as "dell-smm-fan[1-3]" too to make them available as cooling devices. Also update Documentation and fix a minor issue with the alphabetic ordering of the includes.

hwmon: (ltq-cputemp) restrict it to SOC_XWAY

2022-05-10T00:27:24Z

Building with SENSORS_LTQ_CPUTEMP=y with SOC_FALCON=y causes build errors since FALCON does not support the same features as XWAY. Change this symbol to depend on SOC_XWAY since that provides the necessary interfaces.
