2022-07-13hwmon: (lm90) Add support for ADT7481, ADT7482, and ADT7483Guenter Roeck1-0/+38
ADT7481, ADT7482, and ADT7483 are similar to ADT7461, but support two external temperature sensors, similar to MAX6695/6696. They support an extended temperature range similar to ADT7461. Registers for the second external channel can be accessed directly or by using the same method as used by MAX6695/6696. For simplicity, the access method implemented for MAX6695/6696 is used. The chips support PEC (packet error checking). Set the PEC feature flag and let the user decide if it should be enabled or not (it is by default disabled). Even though it is only documented for ADT7483, all three chips support a secondary manufacturer ID register at 0x3e and a chip ID register at 0x3f. Use the contents of those registers register for improved chip detection accuracy. Add the same check to the ADT7461A detection code since this chip also supports the same (undocumented) registers. Devicetree nodes are not added for the added chips since it is quite unlikely that such old chips will ever be used in a devicetree based system. They can be added later if needed.

2022-07-13hwmon: (lm90) Add explicit support for MAX6648/MAX6692Guenter Roeck1-2/+10
Unlike MAX6646/MAX6647/MAX6649, MAX6648 and MAX6692 only support a temperature range of 0..127 degrees C. Separate support for the two sets of chips to be able to support maximum temperature ranges correctly for all chips. Introduce new feature flag to indicate temperature support up to 255 degrees C. Since the chips are almost identical except for the supported temperature range, automatic chip detection is limited. Effectively this means that MAX6648 may be mis-detected as MAX6649 when auto-detected, but there is nothing we can do about that. Devicetree nodes are not added for the added chips since it is quite unlikely that such old chips will ever be used in a devicetree based system. They can be added later if needed.

2022-07-13hwmon: (lm90) Add partial PEC support for ADT7461Guenter Roeck1-0/+1
Revision 0 of the ADT7461 datasheet suggests that the chip supports PEC (packet error checking). This information is gone in later versions of the datasheet. Experiments show that PEC support on ADT7461 is similar to PEC support in ADM1032, ie it is only supported for read operations. Add support for it to the driver. Signed-off-by: Guenter Roeck <[email protected]>
2022-07-13hwmon: (lm90) Improve PEC supportGuenter Roeck1-3/+3
PEC (packet error checking) support for ADM1032 is currently only enabled if the chip was auto-detected, but not if a chip is instantiated explicitly. Always enable PEC support by introducing a chip feature flag indicating partial PEC support. Also, for consistency, disable PEC support by default to match existing functionality if the chip was not auto- detected. At the same time, introduce generic support for PEC with a separate feature flag. This will be used when support for chips with full PEC functionality is added.

2022-07-13hwmon: (pmbus) Move pec attribute to I2C deviceGuenter Roeck1-0/+9
Enabling and disabling PEC for PMBus devices is currently only supported with a debugfs attribute, which requires debugfs to be enabled and is thus less than perfect. Take the lm90 driver as example and add a 'pec' attribute to the I2C device if both the I2C adapter and the PMBus device support it. Remove the now obsolete 'pec' attribute from debugfs.

2022-05-22hwmon: Make chip parameter for with_info API mandatoryGuenter Roeck1-1/+1
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]>

This driver implements monitoring and control of fans plugged into the device. Besides typical speed monitoring and PWM duty cycle control, voltage and current are reported for every fan. The device also has 2 connectors for RGB LEDs, support for them isn't implemented (mainly because there is no standardized sysfs interface). Also, the device has a noise sensor, but the sensor seems to be completely useless (and very imprecise), so support for it isn't implemented too. The driver coexists with userspace tools that access the device through hidraw interface with no known issues. The driver has been tested on x86_64, built in and as a module.

2021-12-26hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.Denis Pauk2-0/+39
Linux HWMON sensors driver for ASUS motherboards to read sensors from the embedded controller. Many ASUS motherboards do not publish all the available sensors via the Super I/O chip but the missing ones are available through the embedded controller (EC) registers. This driver implements reading those sensor data via the WMI method BREC, which is known to be present in all ASUS motherboards based on the AMD 500 series chipsets (and probably is available in other models too). The driver needs to know exact register addresses for the sensors and thus support for each motherboard has to be added explicitly. The EC registers do not provide critical values for the sensors and as such they are not published to the HWMON.

2021-10-27hwmon: (tmp401) Drop support for TMP461Guenter Roeck1-14/+1
TMP461 is almost identical to TMP451, which is already supported by the lm90 driver. At the same time, unlike other sensors from the TMP401 compatible series, it only supports 8-bit temperature read operations, and it supports negative temperatures when configured for its default temperature range, and it supports a temperature offset register. Supporting this chip in the tmp401 driver adds unnecessary complexity. Remove its support from this driver and support the chip with the lm90 driver instead. Fixes: 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T. Wilson <[email protected]> Cc: David T.

2021-10-27hwmon: (lm90) Add basic support for TI TMP461Guenter Roeck1-0/+10
TMP461 is almost identical to TMP451 and was actually detected as TMP451 with the existing lm90 driver if its I2C address is 0x4c. Add support for it to the lm90 driver. At the same time, improve the chip detection function to at least try to distinguish between TMP451 and TMP461. As a side effect, this fixes commit 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations"). TMP461 does not support word operations on temperature registers, which causes bad temperature readings with the tmp401 driver. The lm90 driver does not perform word operations on temperature registers and thus does not have this problem. Support is listed as basic because TMP461 supports a sensor resolution of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125 degrees C. Also, the TMP461 supports negative temperatures with its default temperature range, which is not the case for similar chips supported by the lm90 and the tmp401 drivers. Those limitations will be addressed with follow-up patches. Fixes: 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T.

2021-10-16hwmon: (dell-smm) Add support for fanX_min, fanX_max and fanX_targetArmin Wolf1-0/+3
The nominal speed of each fan can be obtained with i8k_get_fan_nominal_speed(), however the result is not available from userspace. Change that by adding fanX_min, fanX_max and fanX_target attributes. All are RO since fan control happens over pwm. Tested on a Dell Inspiron 3505 and a Dell Latitude C600.

2021-10-12hwmon: (pmbus/lm25066) Support configurable sense resistor valuesZev Weiss1-0/+2
The appropriate mantissa values for the lm25066 family's direct-format current and power readings are a function of the sense resistor employed between the SENSE and VIN pins of the chip. Instead of assuming that resistance is always the same 1mOhm as used in the datasheet, allow it to be configured via a device-tree property ("shunt-resistor-micro-ohms").
