2022-01-23hwmon: (lm90) Re-enable interrupts after alert clearsGuenter Roeck1-1/+1
If alert handling is broken, interrupts are disabled after an alert and re-enabled after the alert clears. However, if there is an interrupt handler, this does not apply if alerts were originally disabled and enabled when the driver was loaded. In that case, interrupts will stay disabled after an alert was handled though the alert handler even after the alert condition clears. Address the situation by always re-enabling interrupts after the alert condition clears if there is an interrupt handler.

2022-01-23hwmon: (lm90) Reduce maximum conversion rate for G781Guenter Roeck1-1/+1
According to its datasheet, G781 supports a maximum conversion rate value of 8 (62.5 ms). However, chips labeled G781 and G780 were found to only support a maximum conversion rate value of 7 (125 ms). On the other side, chips labeled G781-1 and G784 were found to support a conversion rate value of 8. There is no known means to distinguish G780 from G781 or G784; all chips report the same manufacturer ID and chip revision. Setting the conversion rate register value to 8 on chips not supporting it causes unexpected behavior since the real conversion rate is set to 0 (16 seconds) if a value of 8 is written into the conversion rate register. Limit the conversion rate register value to 7 for all G78x chips to avoid the problem. Fixes: ae544f64cc7b ("hwmon: (lm90) Add support for GMT G781") Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2021-12-26hwmon: add driver for NZXT RGB&Fan Controller/Smart Device v2.Aleksandr Mezin3-0/+840
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. Some changes/improvements were suggested by Jonas Malaco.

The only purpose of i8k_ioctl() is to call i8k_ioctl_unlocked() with i8k_mutex held.

2021-12-26hwmon: (ntc_thermistor) Drop read_uv() depend on OF and IIOLinus Walleij2-38/+16
The only possible assignment of a function to get a voltage to convert to a resistance is to use the internal function ntc_adc_iio_read() which is only available when using IIO and OF. Bite the bullet and mandate OF and IIO, drop the read_uv() callback abstraction and some ifdefs. As no board is using the platform data, all users are using OF and IIO anyway.

2021-12-26hwmon: (ntc_thermistor) Merge platform data into driverLinus Walleij1-5/+36
Platform data is supposed to be used with "board files", device descriptions in C. Since the introduction of the NTC driver in 2011, no such platforms have been submitted to the Linux kernel, and their use is strongly discouraged in favor of Device Tree, ACPI or as last resort software firmware nodes. Drop the external header and copy the platform data into the driver file.

2021-12-26hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.Denis Pauk3-0/+634
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. Supported motherboards: * PRIME X570-PRO * Pro WS X570-ACE * ROG CROSSHAIR VIII HERO * ROG CROSSHAIR VIII DARK HERO * ROG CROSSHAIR VIII FORMULA * ROG STRIX X570-E GAMING * ROG STRIX B550-I GAMING * ROG STRIX B550-E GAMING Co-developed-by: Eugene Shalygin <eugene.shalygin@gmail.com> Signed-off-by: Eugene Shalygin <eugene.shalygin@gmail.com> Co-developed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Denis Pauk <pauk.denis@gmail.com> Tested-by: Tor Vic <torvic9@mailbox.org> Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2021-12-26hwmon: (tmp401) Hide register write address differences in regmap codeGuenter Roeck1-44/+25
Since we are using regmap access functions to write into chip registers, we can hide the difference in register write addresses within regmap code. By doing this we do not need to clear the regmap cache on register writes, and the high level code does not need to bother about different read/write register addresses.
