[PATCH v1 0/7] iio:st_pressure: improvements

[Gregor Boirie <gregor.boirie@parrot.com>]

This follows up on various comments related to the preliminary patch series
found at http://www.spinics.net/lists/linux-iio/msg24239.html

What you'll find here :
* make st_pressure sensors compliant with IIO ABI ;
* fix the way st_sensors samples are stored in memory to comply with IIO
  expected alignment constraints ;
* add support for temperature triggered buffering ;
* enhance LPS22HB support.

Changes since preliminary series :
* drop patches already applied onto testing branch
* 1st patch is a rebase of Jonathan's fixes-togreg branch d43a411 commit onto
  testing branch
* reorder patches to move fix patches ahead of series
* document sampling gains and datasheets in a separate patch
* rebase of other patches on top of testing branch
* complete LPS22HB support with Linus' open drain mode

Tested with the following Linus' fixes-togreg branch patches applied :
9914760 iio: st_sensors: Disable DRDY at init time
ff05916 iio: st_sensors: Init trigger before irq request
65925b6 iio: st_sensors: switch to a threaded interrupt

Regards,
gregor.
