software trigger).

7247645f68 iio: hmc5843: Move hmc5843 out of staging
This patch moves hmc5843 driver from staging/iio/magnetometer
to iio/magnetometer, updates the corresponding Makefiles and
moves the hmc5843* entries to the 'Industrial I/O support ->
Magnetometer sensors' menu.

c91746a236 iio: magn: Add support for BMC150 magnetometer
Add support for the Bosh BMC150 Magnetometer.
The specification can be downloaded from:
http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf.
The chip contains both an accelerometer and a magnetometer.
This patch adds support only for the magnetometer part.

The temperature compensation formulas are based on bmm050_api.c

8493585317 iio: Allow compile test of GPIO consumers if !GPIOLIB
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

d14c0f10e7 iio: AK09911 : 3 axis compass support
Added IIO magnetometer driver for AK09911. In functionality is resembles
AK8975 or AK8963. But there are several differences, so instead of
modifying existing AK8975 driver and keep it clean, implemented as
a separate driver.
The key differences are:
- Register map is different and have different indexes
- AK09911 is a very compact interface with no DRDY pin. So no support
 of interrupt or GPIO poll
- Even for polled mode no mention on ST2 register, which is required in
ak8975 driver
- mode values are different for fuse access

6027c077f6 iio: ak8975 : Add AK8963 compatibility mode support
AK8963 and AK8975 use same register definitions, except the range
of X,Y,Z values. Added support of 8963 based on i2c_device_id.
Unfortunately there is no way to detect the type via registers,
both device registers return 0x48 as id of chipset.

3edc84e605 iio: Add a comment to about alphabetical order to Kconfigs and Makefiles
Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of
conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to
document that the entries should be kept in alphabetical order.

Also reorder those  entries which weren't in alphabetical order yet.
