This module (bmx055) implements support for the following core Bosch chipsets: bma250e - accelerometer, 3 variants (chip id's 0x03, 0xf9, and 0xfa) bmm150 - magnetometer bmg160 - gyroscope The other 3 devices are combinations of the above: bmx055 - accel/gyro/mag bmc160 - accel/mag bmi055 - accel/gyro ...for 6 devices total. For the combination devices, all of the sub-devices appear as individual independent devices on the I2C/SPI bus. The combination drivers provide basic configuration and data output. For more detailed control as well as interrupt support, you should use the core device drivers (accel/gyro/mag) directly. These devices support both I2C and SPI communications. They must be powered at 3.3vdc. Signed-off-by: Jon Trulson <jtrulson@ics.com>
