Add support for InvenSense mpu3050/6000 Gyroscope chip The driver is used to support gyroscope device, and it provides an interface to control accelerometer and e-compass (optional).
The driver also provides sysfs and input event for Meego's sensor framework. Based on linux-kernel-2.6.35 doesn't have support for gyroscope device, would Meego accept this patch into mid-ref tree?
