This patch adds minimal driver for the Honeywell Amplified Basic Pressure sensors series. Sensors are pretty simple but are available in many variants: - psi/mbar/kPa output, - analog/i2c/spi, - gage/differential measurement, - different measure ranges etc. Refer to datasheets for more details: http://sensing.honeywell.com/honeywell-sensing-basic-board-mount-pressure-sensors-abp-series-datasheet-323005128-c-en.pdf http://sensing.honeywell.com/index.php%3Fci_id%3D45841 Driver internals: - i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c bus doesn't support it, it is required to send a dummy byte to trigger measurement, - since iio sysfs expects kilopascals, mbar-variants are treated as their respective kPa-s, hence i2c id-table has doubled entries in one line: { "abp060mg", ABP006KG }, { "abp006kg", ABP006KG }, - psi-variants have prescaled values in config, - no temperature reads yet. Work remained: - optional temperature channel, - SPI support, - DT binding. Changes since v1: - mutex is now locked in read_raw(), - corrected error codes, - fixed coding style issues, - renamed few defines and functions abp -> abp060mg (some structs left as they were to keep the sensible meaning).
