2020-09-03iio: accel: bma220: Drop ACPI_PTR() and accompanying ifdefferyAndy Shevchenko1-4/+2
The driver is quite likely used only on ACPI based platforms and rarely build with CONFIG_ACPI=n. Even though, the few dozens of bytes is better than ugly ifdeffery and inclusion of heavy header. As a result, replace acpi.h with mod_devicetable.h.

2020-09-03iio: accel: adxl372: Add support for FIFO peak modeStefan Popa1-12/+299
By default, if all three channels (x, y, z) are enabled, sample sets of concurrent 3-axis data is stored in the FIFO. This patch adds the option to configure the FIFO to store peak acceleration (x, y and z) of every over-threshold event. When pushing to iio buffer we push only enabled axis data. Currently the driver configures adxl372 to work in loop mode. The inactivity and activity timings decide how fast the chip will loop through the awake and waiting states and the thresholds on x,y,z axis decide when activity or inactivity will be detected. This patch adds standard events sysfs entries for the inactivity and activity timings: thresh_falling_period/thresh_rising_period and for the in_accel_x_thresh_falling/rising_value.

2020-09-03iio:temperature:mlx90632: Adding extended calibration optionCrt Mori1-2/+216
For some time the market wants medical grade accuracy in medical range, while still retaining the declared accuracy outside of the medical range within the same sensor. That is why we created extended calibration which is automatically switched to when object temperature is too high. This patch also introduces the object_ambient_temperature variable which is needed for more accurate calculation of the object infra-red footprint as sensor's ambient temperature might be totally different than what the ambient temperature is at object and that is why we can have some more errors which can be eliminated. Currently this temperature is fixed at 25, but the interface to adjust it by user (with external sensor or just IR measurement of the other object which acts as ambient), will be introduced in another commit.
