2012-11-22misc: remove use of __devinitBill Pemberton1-1/+1
CONFIG_HOTPLUG is going away as an option so __devinit is no longer needed.

2012-04-19misc: add support for bmp18x chips to the bmp085 driverEric Andersson1-96/+67
The bmp18x chip family comes in an I2C respectively SPI variant. Hence, the bmp085 driver was split to support both buses.

2010-08-10drivers/misc: support for the pressure sensor BMP085 from Bosch SensortecChristoph Mair1-0/+482
This driver adds support for the BMP085 digital pressure sensor from Bosch Sensortec. It exposes a sysfs api to userspace where pressure and temperature measurement results can be read from the pressure0_input and temp0_input file. The chip is able to calculate the average of up to eight samples to increase the accuracy. This feature can be controlled by writing to the oversampling file. The BMP085 digital pressure sensor can measure ambient air pressure and temperature. Both values can be obtained from sysfs files. The pressure is measured by reading from pressure0_input. Valid values range from 30000 to 110000 pascal with a resolution of 1 pascal (=0.01 millibar). temp0_input holds the current temperature in degree celsius, multiplied by 10. This results in a resolution of a tenth degree celsius. Values range from -400 to 850. To increase the accuracy, this chip can calculate the average of 1, 2, 4 or 8 samples. This behavior is controlled through the oversampling sysfs file. Two to the power of the value written to that file specifies how many samples will be used. Valid values: 0..3.
