[PATCH 0/9] iio mount matrix - revitalize missing bindings documentation and provide code for bmc150, bmg160, bma180, itg3200, hmc584x

[H. Nikolaus Schaller]

This patch series adds the mount-matrix to several iio sensor drivers
used in handheld devices.

The mount-matrix translates the quite arbitrary orientation of the sensor
on some printed circuit board to user-tangible orientation in handheld
devices that relates to typical screen orientation.

There was a bindings documentation by Linus Walleij but the patch
did not make it into mainline. Therefore I resend it here.

Next I have added some clarifications (at least I hope it clarifies)
in a second patch.

Finally, the patch set implements the hooks for the mount matrix
in several iio drivers: bmc150, bma180, bmg160, itg3200, hmc5843.
This includes also one patch for the bma180 to convert it to devm API.

We use them in different variants of the omap3-gta04 so a separate
patch set will provide device tree additions for them.
