iio/imu: inv_icm42600: Use max() helper macros Use the standard max() helper macros instead of direct variable comparison using if/else blocks or ternary operator. Change identified using minmax.cocci Coccinelle semantic patch.

iio: move inv_icm42600 timestamp module in common Create new inv_sensors common modules and move inv_icm42600 timestamp module inside. This module will be used by IMUs and also in the future by other chips. Modify inv_icm42600 driver to use timestamp module and do some headers cleanup.

iio: imu: inv_icm42600: fix timestamp reset Timestamp reset is not done in the correct place. It must be done before enabling buffer. The reason is that interrupt timestamping is always happening when the chip is on, even if the corresponding sensor is off. When the sensor restarts, timestamp is wrong if you don't do a reset first.

iio: imu: inv_icm42600: add accurate timestamping Add a timestamping mechanism for buffer that provides accurate event timestamps when using watermark. This mechanism estimates device internal clock by comparing FIFO interrupts delta time and device elapsed time computed by parsing FIFO data. Take interrupt timestamp in hard irq handler and add IIO device specific timestamp structures in device private allocation.
