* Staging: IIO: Periodic timer based triggerJonathan Cameron2009-09-155-1/+254
| | | | | | | | | | | | | | The original posting of this driver led to a discussion in which it was commented that a better system was needed for dealing with the many possible periodic interrupt sources available on some SoCs. Unfortunately that is a big task and as far as I know, no-one has taken it on as yet. So in the meantime this driver is still in here.

* Staging: IIO: lis3l02dq ring buffer and data ready trigger supportJonathan Cameron2009-09-153-1/+621
| | | | | | | | | | | | | | | 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: Ring buffer: Initial pass at rarely locked ring bufferJonathan Cameron2009-09-154-0/+636
| | | | | | | | | | | | | | | | | | | Please note this ring buffer implementation is very much a work in progress (and hence RFC). In it's current form it is stable and reasonably efficient. There are a couple of unlikely cases that will lead to more data being lost that is strictly necessary. The target was for the case of requiring regular sampling even during user space reads. All comments welcome. The intention is to make this only one of several implementations with run time selection. For now there is only one, so it is hard coded into the drivers using it.

* Staging: IIO: Trigger support added to core.Jonathan Cameron2009-09-155-1/+579
| | | | | | | | | | | | | | | | | | | | | | | | | Add general registration support for IIO triggers. These are currently only used to initialize a 'poll' of a given device. Examples include the lis3l02dq's data ready signal being used to initialize a read and gpio triggers being used to allow externally synchronized sensor reading. Each trigger can cause any number of 'consumer' devices to be polled with each storing data into a related ring buffer. Two stage triggering is supported with 'fast' and 'slow' paths. The first is used for things like pulling a data hold line high and the second for actual read which may take far longer. Changes since V2: * As with IIO triggers now use a registration approach much closer to that of input leading to cleaner code.

* Staging: IIO: VTI sca3000 series accelerometer driver (spi)Jonathan Cameron2009-09-156-0/+2171
| | | | | | | | | | | | | Example of how a device with a hardware ring buffer is handled within IIO. Changes since V2: * Moved to new registration functions giving much cleaner interface. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Staging: IIO: Add generic ring buffer support to the IIO coreJonathan Cameron2009-09-154-0/+858
| | | | | | | | | | | | | | | | | | This provides a unified interface for hardware and software ring buffers. Changes since V2: * Moved to a more consistent structure. Now the ring buffer has an associated struct device which is a child of the relevant iio_dev. This in turn has two children, one for the event interface and one for the access interface. These two interfaces are now managed via cdev structures. * Numerous minor cleanups Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Staging: IIO: kxsd9 accelerometer minimal supportJonathan Cameron2009-09-154-0/+417
| | | | | | | | | | | | | | | | This provides only very minimal support for this device. Note that an alternate driver has been posted to the input mailing list. When the original LMKL discussion that led to the descision to develop IIO occured, the question on whether the differing requirements of IIO and input drivers made it a good idea to have unified drivers was left as an open question. It still is. All opinions on this question welcome. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | This was done using a semantic patch (http://coccinelle.lip6.fr/) that checks that the declaration is not inside a function definition, that the defined variable is not exported using EXPORTED_SYMBOL, etc, and that the defined variable does not occur in any other file.
