Naveen Krishna Chatradhi 927b4dc3e4 iio: exynos_adc: fix wrong structure extration in suspend and resume
The exynos_adc device structure was wrongly extracted from the dev*
correcting the same.

Using the regular conversion of
struct device* -> struct platform_device* -> struct exynos_adc* seems wrong.
Instead we should be doing
struct device* -> struct iio_dev* -> struct exynos_adc*

Jean-Christophe PLAGNIOL-VILLARD beca9e767e iio: at91_adc: fix missing Sample and Hold time
On the at91_adc a minimal Sample and Hold Time is necessary for the ADC to
guarantee the best converted final value between two channels selection.
This time has to be programmed through the bitfield SHTIM in the
Mode Register ADC_MR.

Ludovic Desroches 47be16b668 iio: at91_adc: add low and high res support
at91 adc offers the choice between two resolutions: low and high.
The low and high resolution values depends on adc IP version, as many IP
properties have been exposed through device tree, these settings have also
been added to the dt bindings.

Lars-Peter Clausen 1e9663c62b iio:trigger: Introduce iio_tigger_{set,get}_drvdata
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>

Lars-Peter Clausen ecf6ca2539 iio:ad7923: Implement scale reporting
The driver already claims to support scale reporting in its channel spec, but
doesn't actually implement this yet. This patch uses the regulator API to get
the reference voltage and calculates the scale based on that. The patch also
moves the global configuration bits into a field in the ad7923_state struct,
since depending on the RANGE bit, the range goes either from 0 to VREF or from 0
to 2 * VREF. So we need to know the setting of the RANGE bit when calculating
the scale.

New drivers
 1) A driver for ST microelectronics sensors.  This driver already covers
    a large set of new parts (20 gyros, accelerometer and magnetometers)
    not currently covered by the existing drivers.  The intent moving forward
    is to merge this with the other drivers for similar parts already in tree.
    The lis3l02dq driver currently in staging/iio will be trivial, the lis3
    driver in misc more complex as it has a number of additional interfaces.
    Any merging in of the lis3 driver will rely on the not currently
    merged iio_input bridge driver and handling of freefall notifications
    etc.
 
 2) A driver for the itg3200 gyroscope.
 
 Graduations from staging
 1) Cleanup and move out of staging of the adxrs450 gyroscope driver.  The
    cleanup required was all minor but there were a couple of fixes hidden in
    there.
 
 Core and driver additions
 1) Initial work from Guenter Roeck on device tree support for IIO's provider/
    consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver.
    The full device tree syntax is currently under discussion but should
    follow shortly.

 1) Remove a noop function __iio_update_buffer
 2) Couple of small fixes and cleanups for the max1363

Guenter Roeck 482bb4e6c6 iio/adc: (max1363) Fix data conversion problems
For chips with more than 8 bit ADC resolution, received data was always
masked against 0xfff, ie with a 12 bit mask. This can result in bad data
for chips with 10 bit resolution if those chips have higher bits set
(seen with MAX1139).

The receive buffer was defined as char array. This could result in
unintentional sign extensions if the upper bit in a received byte
was set. Since the chip is configured for unipolar mode, we never
have to handle negative values, and sign extensions are never needed.

Linus Torvalds 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.

Merge tag 'staging-3.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging fixes from Greg Kroah-Hartman:
 "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.

Greg Kroah-Hartman 17cb3be61b Merge branch 'staging-linus' into staging-next
This is to get the comedi fixes, and resolve the issue in comdi_test.c
and comedi_fops.c that were caused by changes in both branches.

It also allows the fwserial driver changes to be applied, as they
required the fixes that are in staging-linus.

Kim, Milo dc11699908 iio: lp8788_adc: fix a parent device in _probe()
The lp8788-adc is a platform driver of lp8788-mfd.
 The platform device is allocated when mfd_add_devices() is called
 in lp8788-mfd.
 On the other hand, 'lp->dev' is the i2c client device.

 Therefore, this 'platform_device' is a proper parent device of
 iio device and device kernel message.

Greg Kroah-Hartman fc52692c49 Drivers: iio: remove __dev* attributes.
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.

Guenter Roeck 678fb42e2b iio: (max1363) Fix probe error path
Instantiating the driver with no available regulator results in:

[39711.686393] i2c i2c-7: new_device: Instantiated device max1139 at 0x35
[39711.688687] BUG: unable to handle kernel paging request at fffffffffffffe13

[39711.688835] Oops: 0000 [#1] SMP

Caused by bad probe error path. Fix it.

Driver should also not attempt to free the interrupt in its error path if
none was allocated. Fix that problem as well.

Finally, testing if the regulator was allocated is not necessary in the
remove function, since the probe function bails out if this is the case.
Remove that check.

Linus Torvalds 2dfea3803d This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub devices
 drivers:
 
 - Austria Microsystem's AS3711
 - Nano River's viperboard
 - TI's TPS80031, AM335x TS/ADC,
 - Realtek's MMC/memstick card reader
 - Nokia's retu
 
 We also got some notable cleanups and improvements:
 
 - tps6586x got converted to IRQ domains.
 - tps65910 and tps65090 moved to the regmap IRQ API.
 - STMPE is now Device Tree aware.
 - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
   APIs and a conversion to the recently added PWM framework.
 - sta2x11 gained regmap support.
 
 Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
 wm5xxx and wm8xxx patchset.

Far amount of annoying but largely trivial conflicts.  Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.
