The conversion (sample) time is configurable for several chips supported by the lm75 driver. With the necessary infrastructure in place, enable this support for all chips using the configuration register for this purpose. DS1775: Conversion time: 187.5, 375, 750, 1500 ms Sensor resolution: 9, 10, 11, 12 bit DS75, STDS75: Conversion time: 150, 300, 600, 1200 ms Sensor resolution: 9, 10, 11, 12 bit DS7505: Conversion time: 25, 50, 100, 200 ms Sensor resolution: 9, 10, 11, 12 bit MCP980[0123]: Conversion time: 75, 150, 300, 600 ms Sensor resolution: 9, 10, 11, 12 bit TMP100, TMP101: Conversion time: 75, 150, 300, 600 ms Sensor resolution: 9, 10, 11, 12 bit TMP75, TMP105, TMP175, TMP275: Conversion time: 38, 75, 150, 300 ms Sensor resolution: 9, 10, 11, 12 bit While doing this, it became obvious that the masks and values to set the converion (sample) time is similar for all those chips, and that other chips with configurable sample times will need separate code anyway. For that reason, replace the sample_set_masks and sample_clr_mask configuration parameters with a single array and with a constant. Signed-off-by: -

There is no reason why power channel shouldn't be exported as is done for voltage, current, temperature and humidity. Power channel is available on iio ina226 driver. Sysfs IIO documentation for power attribute added by commit 7c6d5c7e ("iio: Documentation: Add missing documentation for power attribute") is declaring that value is in mili-Watts but hwmon interface is expecting value in micro-Watts that's why there is a need for mili-Watts to micro-Watts conversion.

I have been using SENSORS_W83795_FANCTRL for several years and never had any problem. When the driver was added, I had not tested that part of the driver yet so I wanted to be super cautious, but time has shown that it works just fine. In the long run I even believe that we should drop the option and enable the feature unconditionally. It doesn't do anything until the user explicitly starts twiddling with sysfs attributes anyway.

At boot time, the acpi_power_meter driver logs the following error level message: "Ignoring unsafe software power cap". Having read about it from a few sources, it seems that the error message can be quite misleading. While the message can imply that Linux is ignoring the fact that the system is operating in potentially dangerous conditions, the truth is the driver found an ACPI_PMC object that supports software power capping. The driver simply decides not to use it, perhaps because it doesn't support the object. The best solution is probably changing the log level from error to warning. All sources I have found, regarding the error, have downplayed its significance. There is not much of a reason for it to be on error level, while causing potential confusions or misinterpretations.

It would seem like model 70h is behaving in the same way as model 30h, so let's just add the new F3 PCI ID to the list of compatible devices. Unlike previous Ryzen/Threadripper, Ryzen gen 3 processors do not need temperature offsets anymore. This has been reported in the press and verified on my Ryzen 3700X by checking that the idle temperature reported by k10temp is matching the temperature reported by the firmware. Vicki Pfau sent an identical patch after I checked that no-one had written this patch. I would have been happy about dropping my patch but unlike for his patch series, I had already Cc:ed the x86 people and they already reviewed the changes. Since Vicki has not answered to any email after his initial series, let's assume she is on vacation and let's avoid duplication of reviews from the maintainers and merge my series. To acknowledge Vicki's anteriority, I added her S-o-b to the patch. v2, suggested by Guenter Roeck and Brian Woods: - rename from 71h to 70h Signed-off-by:

The AMD Ryzen gen 3 processors came with a different PCI IDs for the function 3 & 4 which are used to access the SMN interface. The root PCI address however remained at the same address as the model 30h. Adding the F3/F4 PCI IDs respectively to the misc and link ids appear to be sufficient for k10temp, so let's add them and follow up on the patch if other functions need more tweaking.
