Linus Torvalds 53ee983378 Staging driver patches for 3.17-rc1
Here's the big pull request for the staging driver tree for 3.17-rc1.
 
 Lots of things in here, over 2000 patches, but the best part is this:
  1480 files changed, 39070 insertions(+), 254659 deletions(-)
 
 Thanks to the great work of Kristina Martšenko, 14 different staging
 drivers have been removed from the tree as they were obsolete and no one
 was willing to work on cleaning them up.  Other than the driver
 removals, loads of cleanups are in here (comedi, lustre, etc.) as well
 as the usual IIO driver updates and additions.
 
 All of this has been in the linux-next tree for a while.

Martin Fuzzey a3fb96a8c0 iio: mma8452: add DT support
Allow the mma8452 to be described in the device tree.

Since no device specific binding attributes exist the trivial
I2C binding is sufficient to describe the compatible string.

Martin Fuzzey 71702e6e52 iio: mma8452: Use correct acceleration units.
The userspace interface for acceleration sensors is documented as using
m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio]

The fullscale raw value for the mma8452 (-2048) corresponds to -2G, -4G or -8G
depending on the seleted mode.

The scale table was converting to G rather than m/s^2.
Change the scaling table to match the documented interface.
