Add regulator supply into PWBUS_REGULATOR macro. This makes it optional to define a vin-supply in DT. Not defining a supply will add a dummy regulator supply instead and only cause the following debug output: ``` Looking up vin-supply property in node [...] failed ``` Signed-off-by:

On the Dell Inspiron 3505, three temperature sensors are available through the SMM interface. However since they do not have an associated type, they are not detected. Probe for those sensors in case no type was detected. _i8k_get_temp() is used instead of i8k_get_temp() since it is sometimes faster and the result is easier to check (no -ENODATA) since we do not care about the actual temp value. Tested on a Dell Inspiron 3505. Signed-off-by:

Right now, we only use bits 0 to 7 of the fan/temp sensor number by doing number & 0xff. Passing the value as a u8 makes this step unnecessary. Also add checks to the ioctl handler since users might get confused when passing 0x00000101 does the same as passing 0x00000001. Tested on a Dell Inspiron 3505. Signed-off-by:

Document the SMM interface as requested by Pali Rohar. Since Dell does not offer any offical documentation regarding the SMM interface, the necessary information was extracted from the dell_smm_hwmon driver and other sources. Suggested-by:

When enabling said module parameter, the driver ignores all feature blacklists on relevant models, which has the potential for strange side effects. Also there seems to be a slight chance for unsupported devices to behave badly when probed for features. In such cases, the kernel should be tainted to inform people that these issues might have been caused by the dell_smm_hwmon driver with "force" enabled. Also reword the parameter description to remind users that enabling "force" also enables blacklisted features. Tested on a Dell Inspiron 3505. Signed-off-by:

Remove the call to dev_info() from the board detection function, which is called from probe(), not only to be in line with hwmon driver rules, but also because the message duplicates the error code returned from probe() for that case (ENODEV).

While these chips aren't strictly advertised as voltage regulators per se, they (aside from the lm25056) support the PMBus OPERATION command to enable and disable their outputs and have status bits for reporting various warnings and faults, and can hence usefully support all the pmbus_regulator_ops operations.

Reading DSDT code for ASUS X470-based boards (the ones served by the asus_wmi_Sensors driver), where ASUS put hardware monitoring functions into the WMI code, reveals that fan and current sensors data is unsigned. For the current sensor that was confirmed by a user who showed high enough current value for overflow. Thus let's assume that the signedness of the sensors is determined by its type and that only temperature ones provide signed numbers. Signed-off-by:

It is not the laptops, but the /proc/i8k interface that is legacy (or so I think was the intention of the help text author). The old description was confusing, fix this. The phrase "Say Y if you intend to run this kernel on old Dell laptops or want to use userspace package i8kutils." was introduced in 2015, in commit 039ae585 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k") I think that "old laptops" was about hotkey and Fn key support - this driver in the 2.4 kernels' era apparently had these capabilities (see: https://github.com/vitorafsr/i8kutils , description of "repeat_rate" kernel module parameter).

In Kconfig, inside the "Processor type and features" menu, there is the CONFIG_I8K option: "Dell i8k legacy laptop support". This is very confusing - enabling CONFIG_I8K is not required for the kernel to support old Dell laptops. This option is specific to the dell-smm-hwmon driver, which mostly exports some hardware monitoring information and allows the user to change fan speed. This option is misplaced, so move CONFIG_I8K to drivers/hwmon/Kconfig, where it belongs. Also, modify the dependency order - change select SENSORS_DELL_SMM to depends on SENSORS_DELL_SMM as it is just a configuration option of dell-smm-hwmon. This includes changing the option type from tristate to bool. It was tristate because it could select CONFIG_SENSORS_DELL_SMM=m . When running "make oldconfig" on configurations with CONFIG_SENSORS_DELL_SMM enabled , this change will result in an additional question (which could be printed several times during bisecting). I think that tidying up the configuration is worth it, though. Next patch tweaks the description of CONFIG_I8K.

A user discovered [1] the CPU Core voltage sensor, which spans 2 registers and provides output in mV. Althroug the discovery was made with a X470 chipset, the sensor is present in X570 (tested with C8H). For now simply add it to each board with the CPU current sensor present.

Using regmap lets us use the regmap subsystem for SPI vs. I2C register accesses. It lets us hide access differences in backend code and lets the common code just access registers without knowing their size. We can also use regmap for register caching. Tested-by:

Temperature sensor readings are signed, which is hinted by their blank value (oxd8, 216 as unsigned and -40 as signed). T_Sensor, Crosshair VIII Hero, and a freezer were used to confirm that. Here we read fan sensors as signed too, because with their typical values and 2-byte width, I can't tell a difference between signed and unsigned, as I don't have a high speed chipset fan.

Recently 'cur_state' user space 'sysfs' interface 'sysfs' has been deprecated. This interface is used in Nvidia systems for setting fan speed limit. Currently fan speed limit is set from the user space by setting 'sysfs' 'cur_state' attribute to 'max_state + n', where 'n' is required limit, for example: 15 for 50% speed limit, 20 for full fan speed enforcement. The purpose of this feature is to provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units (PSU or line cards), high system ambient temperature, unreliable transceivers temperature sensing or some other factors which indirectly impacts system's airflow. The motivation is to support fan low limit feature through 'hwmon' interface. Use 'hwmon' 'pwm' attribute for setting low limit for fan speed in case 'thermal' subsystem is configured in kernel. In this case setting fan speed through 'hwmon' will never let the 'thermal' subsystem to select a lower duty cycle than the duty cycle selected with the 'pwm' attribute. From other side, fan speed is to be updated in hardware through 'pwm' only in case the requested fan speed is above last speed set by 'thermal' subsystem, otherwise requested fan speed will be just stored with no PWM update.

This driver provides the same data as the asus_wmi_ec_sensors driver (and gets it from the same source) but does not use WMI, polling the ACPI EC directly. That provides two enhancements: sensor reading became quicker (on some systems or kernel configuration it took almost a full second to read all the sensors, that transfers less than 15 bytes of data), the driver became more flexible. The driver now relies on ACPI mutex to lock access to the EC in the same way as the WMI code does. Signed-off-by:

If the watchdog was already enabled by the BIOS after booting, the watchdog infrastructure needs to regularly send keepalives to prevent a unexpected reset. WDOG_ACTIVE only serves as an status indicator for userspace, we want to use WDOG_HW_RUNNING instead. Since my Fujitsu Esprimo P720 does not support the watchdog, this change is compile-tested only.

This patch enables the sch56xx-common module to get automatically loaded on supported machines. If a machine supports Fujitsu's SCH56XX-based hardware monitoring solutions, it contains a "Antiope"/" Antiope" dmi onboard device in case of the sch5627 or a "Theseus"/" Theseus" dmi onboard device in case of the sch5636. Since some machines like the Esprimo C700 have a seemingly faulty DMI table containing both onboard devices, the driver still needs to probe for the individual superio chip, which in presence of at least one DMI onboard device however can be considered safe. Also add a module parameter allowing for bypassing the DMI check. Tested on a Fujitsu Esprimo P720. Signed-off-by:
