2022-05-22hwmon: Make chip parameter for with_info API mandatoryGuenter Roeck1-9/+7
Various attempts were made recently to "convert" the old hwmon_device_register() API to devm_hwmon_device_register_with_info() by just changing the function name without actually converting the driver. Prevent this from happening by making the 'chip' parameter of devm_hwmon_device_register_with_info() mandatory. Signed-off-by: Guenter Roeck <[email protected]>
2022-05-22thermal/drivers/thermal_hwmon: Use hwmon_device_register_for_thermal()Guenter Roeck1-2/+4
The thermal subsystem registers a hwmon device without providing chip information or sysfs attribute groups. While undesirable, it would be difficult to change. On the other side, it abuses the hwmon_device_register_with_info API by not providing that information. Use new API specifically created for the thermal subsystem instead to let us enforce the 'chip' parameter for other callers of hwmon_device_register_with_info(). Acked-by: Rafael J .

2022-05-22hwmon: Introduce hwmon_device_register_for_thermalGuenter Roeck1-0/+25
The thermal subsystem registers a hwmon driver without providing chip or sysfs group information. This is for legacy reasons and would be difficult to change. At the same time, we want to enforce that chip information is provided when registering a hwmon device using hwmon_device_register_with_info(). To enable this, introduce a special API for use only by the thermal subsystem. Acked-by: Rafael J . Wysocki <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>

2022-05-22hwmon: (nct6775) Add i2c driverZev Weiss3-0/+213
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).

2022-05-22hwmon: (pmbus) Register with thermal for PSC_TEMPERATUREEduardo Valentin1-0/+68
Some pmbus device drivers have device tree support and may want to use of-thermal to register a thermal zone OF sensor for those device drivers. This way we allow describing device tree thermal zones for pmbus device drivers with device tree support. This patch achieves this by registering pmbus sensors with thermal subsystem if they are PSC_TEMPERATURE and are providing _input hwmon interface.

This memory holds three double words where the least significant bit tells whether the interrupt cause of master/target/error is valid. The driver does not use this but we need to set it up because otherwise it will perform DMA write to the default address (0) and this will cause an IOMMU fault such as below: DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set To prevent this from happening, provide a proper DMA buffer for this that then gets mapped by the IOMMU accordingly.
