This adds the Samsung 1404-001221 NTC thermistor to the NTC thermistor driver. As far as I can tell it is electrically compatible with the Murata 47K NTC thermistor. This thermistor is mounted in a variety of Samsung products.

The only purpose of i8k_ioctl() is to call i8k_ioctl_unlocked() with i8k_mutex held. Judging from the hwmon code, this mutex only needs to be held when setting the fan speed/mode, so the operation of I8K_SET_FAN is guaranteed to be atomic. Unify both functions and reduce the locking of i8k_mutex to I8K_SET_FAN. Tested on a Dell Inspiron 3505.

The second switch-case has no real purpose: - for I8K_BIOS_VERSION, val does not represent a return value, making the check for error values unnecessary. - for I8K_MACHINE_ID, val remains zero, so the error check is unnecessary too. Remove the switch-case and move the calls to copy_to_user() into the first switch-case for I8K_BIOS_VERSION/_MACHINE_ID. Omit buff[] since data->bios_machineid already contains the string with the necessary zero padding through devm_kzalloc(). Tested on a Dell Inspiron 3505.

This switches to retrieveing the configuration of the NTC from generic firmware properties so that we get neutral from device tree: now ACPI or, more importantly, software nodes can be used to spawn NTC devices provided they have the required properties. This was inspired by the similar changes made to the IIO drivers. This was tested on the Ux500 HREF with the NTC devices probing from device tree just as fine after this as before.

Move the parsing of the DT config right above probe(). Allocate the state container for the driver in probe() instead of inside the DT config parsing function: as a result return an int instead of a pointer. Drop the check for !np: we can only probe from DT right now so no risk of ending up here.

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.

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.

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.

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.

The difference between TMP431 and other chips of this series is that the TMP431 has an additional sensor. The register addresses for other sensors are the same for all chips. It is therefore unnecessary to maintain two different arrays for TMP431 and the other chips. Just use the same array for all chips and add the TMP431 register addresses as third column.
