* Staging: IIO: lis3l02dq ring buffer and data ready trigger supportJonathan Cameron2009-09-151-1/+21
| | | | | | | | | | | | | | | Example of relatively common case of device sampling based on internal clock and providing a data ready signal to indicate that new data is available to be read out. Generic trigger approach used to allow other devices to be sampled 'at the same time' as this the accelerometer. This is very useful in various motion estimation algorithms.

* Staging: IIO: lis3l02dq accelerometer core supportJonathan Cameron2009-09-151-0/+212
A later patch in the series will add data ready triggering and ring buffer support. This core patch provides an event interface and sysfs based reading of values. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
