Unless we put the device to sleep when not it use, it wastes
6mA.
If the device is asleep on probe, the 'id' register
sometimes mis-reads - so reset first. If the device responds
at all a command sent to the address, it is almost certainly
the correct device already.

Here's the big staging tree pull request for 3.19-rc1.
We continued to delete more lines than were added, always a good thing,
but not at a huge rate this release, only about 70k lines removed
overall mostly from removing the horrid bcm driver.
Lots of normal staging driver cleanups and fixes all over the place,
well over a thousand of them, the shortlog shows all the horrid details.
The "contentious" thing here is the movement of the Android binder code
out of staging into the "real" part of the kernel. This is code that
has been stable for a few years now and is working as-is in the tens of
millions of devices with no issues. Yes, the code is horrid, and the
userspace api leaves a lot to be desired, but it's not going to change
due to legacy issues that we have no control over. Because so many
devices and companies rely on this, and the code is stable, might as
well promote it out of staging.
This was all discussed at the Linux Plumbers conference, and everyone
participating agreed that this was the best way forward.
There is work happening to replace the binder code with something new
that is happening right now, but I don't expect to see the results of
that work for another year at the earliest. If that ever happens, and
Android switches over to it, I'll gladly remove this version.
As for maintainers, I'll be glad to maintain this code, I've been doing
it for the past few years with no problems. I'll send a MAINTAINERS
entry for it before 3.19-final is out, still need to talk to the Google
developers about if they are willing to help with it or not, last I
checked they were, which was good.

Add support for the BMI055 gyroscope sensor. BMI055 is a package
consisting of an acceleration sensor and a gyroscope. This patch
adds support for the gyroscope only.
Spec downloaded from:
http://ae-bst.resource.bosch.com/media/products/dokumente/bmi055/BST-BMI055-DS000-06.pdf
The BMI055 gyroscope uses the same register definition as BMG160,
but does not specify a temp register. However, the temp register
seems to be working in the same way as for BMG160, so this patch
does not remove the temp channel for BMI055.

The I2C devices that make up the STMicroelectronics MEMS sensors
may be sneakily enabled by cleverly giving the device node the same
name as a string match from the platform device ID table. However
the right method is to use the compatible string.
On detection, the ST sensors use the ID string to probe and
instatiate the right sensor driver, so pass the kernel-internal ID
string in the .data field of the OF match table, and set the I2C
client name to this name when a compatible match is used.
This avoids having misc Linux-specific strings floating around in
the device tree.

By using the info_mask_shared_by_all element of the channel spec, acce
to the sampling frequency becomes available to in kernel users of the
driver. It also shortens and simplifies the code.
This particular conversion was made more complicated by the shared library
and the fact that a number of the drivers do not actually have support for
setting or reading the sampling frequency. The hardware, in those cases

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.

Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific
data to a trigger. The functions wrap access to the triggers private_data field
and all current users are updated to use iio_tigger_{set,get}_drvdata instead of
directly accessing the private_data field. This is the first step towards
removing the private_data field from the iio_trigger struct.
The following coccinelle script has been used to update the drivers:
<smpl>

struct iio_trigger *trigger;

-trigger->private_data = priv
+iio_trigger_set_drv_data(trigger, priv)

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.

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.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Not much to say, without that change, hid-sensor-trigger will be
always compiled if HID_SENSOR_IIO_COMMON is selected which fails if
CONFIG_IIO_TRIGGER is not set because CONFIG_IIO_CONSUMERS_PER_TRIGGER
will not be defined.

It's slightly cleaner to use kstrtouint() because we pass unsigned ints
to adis16136_set_freq(). On 64 bit systems, if the user passed LONG_MIN
then it we would get past the test against zero but crash in
adis16136_set_freq() because we truncate the high bits away.

Drop timestamp parameter from buffer store_to callback and subsequently from

it will stay unused in the future, so it should be safe to remove it.
