charset="utf-8" This commit intends to add the old BMP085 sensor to the new IRQ interface of the driver for consistence. No functional changes intended. The BMP085 sensor is equivalent with the BMP180 with the only difference of BMP085 having an extra interrupt pin to inform about an End of Conversion.
