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

ea7e586bdd iio: st_sensors: move regulator retrieveal to core
Currently the pressure sensor has code to retrieve and enable two
regulators for Vdd and Vdd IO, but actually these voltage inputs
are found on all of these ST sensors, so move the regulator
handling to the core and make sure all the ST sensors call these
functions on probe() and remove() to enable/disable power.

Here also mover over to obtaining the regulator from the *parent*
device of the IIO device, as the IIO device is created on-the-fly
in this very subsystem it very unlikely evert have any regulators
attached to it whatsoever. It is much more likely that the parent
is a platform device, possibly instantiated from a device tree,
which in turn have Vdd and Vdd IO supplied assigned to it.

bef44abccb iio: ak8975: Fix calculation formula for convert micro tesla to gauss unit
This effects the reported scale of the raw values, and thus userspace
applications that use this value.

One micro tesla equal 0.01 gauss. So I have fixed calculation formula And add RAW_TO_GAUSS macro.
ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is
always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO.
As a result, read_raw call back function return accurate scale value.

2fc72cd835 iio:magnetometer:ak8975 move driver out of staging
Issues raised in last series to propose this have now been resolved
so there should be no reason this driver cannot graduate from staging.

8ce4a56a52 iio:st_sensors fix build when !CONFIG_IIO_TRIGGER
Partly a case of removing unused headers and partly a case
of ifdefing out the iio_trigger_ops structures.  This has
come about because of an 'unusual' separation of code in this
driver.

b87fc3e6e2 Staging fixes for 3.8-rc3
Here are a number of small fixes to staging drivers for your 3.8-rc3
 tree.
 
 Well, the omapdrm fixes aren't really "small" but they were waiting on a
 number of other drm patches to go in through the drm tree, and got
 delayed by my vacation over the holidays.  They are totally
 self-contained, everyone involved have acked them, and they fix issues
 that people have been having with the driver.
 
 Other than that one, it's a bunch of tiny bugfixes for a number of
 reported issues.
