+What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input
+Date:		June 2010
+Contact:	Christoph Mair <christoph.mair@xxxxxxxxx>
+Description:	Start a pressure measurement and read the result. Values
+		represent the ambient air pressure in pascal (0.01 millibar).
+
+		Reading: returns the current air pressure.
+
+
+What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input
+Date:		June 2010
+Contact:	Christoph Mair <christoph.mair@xxxxxxxxx>
+Description:	Measure the ambient temperature. The returned value represents
+		the ambient temperature in units of 0.1 degree celsius.
+
+		Reading: returns the current temperature.
+
+
+What:		/sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling
+Date:		June 2010
+Contact:	Christoph Mair <christoph.mair@xxxxxxxxx>
+Description:	Tell the bmp085 to use more samples to calculate a pressure
+		value. When writing to this file the chip will use 2^x samples
+		to calculate the next pressure value with x being the value
+		written. Using this feature will decrease RMS noise and
+		increase the measurement time.
+
+		Reading: returns the current oversampling setting.
+
+		Writing: sets a new oversampling setting.
+		Accepted values: 0..3.
