+What: /sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input
+Date: June 2010
+Contact: Christoph Mair <christoph.mair@gmail.com>
+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@gmail.com>
+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@gmail.com>
+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.
