[PATCH v2 00/10] iio mount matrix - revitalize missing bindings documentation and provide code for bmc150, bmg160, bma180, itg3200, hmc584x

Fixes V2:
* make get_mount_matrix() functions more readable (use temp variable)
(suggested by Jonathan and Andy)
* add these readability improvements also for ak8975 and mpu6050
(suggested by Jonathan and Andy)
* squash bindings documentation into single commit for better discussion
(suggested by Linus)
* FOR DISCUSSION: add some more clarifications to the bindings documentation
and an attempt to define the magnetometer orientation
* add "iio: Allow to read mount matrix from ACPI" to the beginning of
the series to make it compile
(suggested by Andy)
* replace of_iio_read_mount_matrix() by iio_read_mount_matrix()
(required by "iio: Allow to read mount matrix from ACPI")
* drop patch to convert bma180 to devm (potential race)
(suggested by Jonathan)

PATCH V1 2019-02-20 15:01:02:
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.
