Based on iio testing branch. Depends on this series [1]. This series aims to add hardware trigger support and extend the functionality of the driver. Sensors BMP3xx and BMP5xx have an interrupt pin which can be used in order to inform about a specific event in the sensor. For now, the data ready event is used, and is added as a DRDY interrupt in the driver. The interrupt is supported only in rising modes for now, and it doesn't support latched mode. Other interrupts such as, FIFO-FULL, FIFO-WATERMARK, Out of range values etc. are not supported for the moment, and only the DRDY interrupt is supported. While working on the trigger, FORCED MODE instead of NORMAL MODE was added to the driver for use in the oneshot capture reads. There is no need for the driver to continuously produce data, without using them and without properly notifying the user when those data became available. This can produce high incosistencies between the acquisition time and the readout of the sensor. The data now, in the case of the .read_raw() function is using the FORCED MODE, which samples and calculates the values at that moment. Last commit, is just moving the interrupt interface of a very old sensor to be consistent with the new ones, and no functional changes are intended.
