-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.
