2016-07-04staging:iio:lis3l02dq drop separate driverJonathan Cameron
Retire this venerable driver as the basic support is now in the generic st-sensors accelerometer driver. There are a few missing features in the new driver: * Threshold events. * Access to the calibration adjustment registers (patch shortly) In exchange it brings a cleaner and more maintainable code base that actually gets tested more than once every few years. I'll actually be suprised if anyone other than me has a board with one of these on that is running an up to date kernel. Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-01-26staging:iio:accel:lis3l02dq remove sw_ring support.Jonathan Cameron
The sw_ring buffer is being removed in favour of the kfifo version. This is one of only a couple of driver still supporting its use. This driver will hopefully also be removed in favour of supporting the part in the unified ST accelerometer driver. Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-10-19staging/iio/lis3l02dq: fix building without irq_to_gpioArnd Bergmann
The driver has not been building for some time after the irq_to_gpio function has been removed from the kernel. The only board in the upstream kernel that provides this device is the "Stargate 2", which is also maintained by Jonathan Cameron. Rather than working around the problem by adding new platform data for this driver, this patch uses the of_gpio framework to get to the gpio number. However, the stargate2 code does not (yet) use DT based probing, so it is still broken, but at least building allyesconfig works again.

2011-09-26staging:iio:accel:lis3l02dq ring->buffer renames.Jonathan Cameron
This driver already supports kfifo usage, so the term ring is misleading and hence replaced. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-09-26staging:iio: replacing term ring with buffer in the IIO core.Jonathan Cameron
They aren't always ring buffers, so just use buffer for all naming. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-05-19staging:iio: Rip out helper for software rings.Jonathan Cameron
It seemed like a good idea at the time, it wasn't. The code with this in place is larger and more complex for no real gain. Basically we've cleaned up the core around it so much that this no longer makes sense. Only really effects the lis3l02dq driver.

2011-05-19staging:iio: rationalization of different buffer implementation hooks.Jonathan Cameron
1) move a generic helper function out of ring_sw. It applies to other buffers as well. 2) Get rid of a lot of left over function definitions. 3) Move all the access functions into static structures. 4) Introduce and use a static structure for the setup functions, preenable etc. Some driver conversions thanks to Michael Hennerich (pulled out of patches that would otherwise sit after this).

2009-09-15Staging: IIO: lis3l02dq ring buffer and data ready trigger supportJonathan Cameron
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.
