Jean Delvare 59cf4243e5 hwmon: (ntc_thermistor) Fix dependencies
In commit 9e8269de, support was added for ntc_thermistor devices being
declared in the device tree and implemented on top of IIO. With that
change, a dependency was added to the ntc_thermistor driver:

	depends on (!OF && !IIO) || (OF && IIO)

This construct has the drawback that the driver can no longer be
selected when OF is set and IIO isn't, nor when IIO is set and OF is
not. This is a regression for the original users of the driver.

As the new code depends on IIO and is useless without OF, include it
only if both are enabled, and set the dependencies accordingly. This
is clearer, more simple and more correct.

Linus Torvalds 235c7b9feb Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull main powerpc updates from Ben Herrenschmidt:
 "This time around, the powerpc merges are going to be a little bit more
  complicated than usual.

  This is the main pull request with most of the work for this merge
  window.  I will describe it a bit more further down.

  There is some additional cpuidle driver work, however I haven't
  included it in this tree as it depends on some work in tip/timer-core
  which Thomas accidentally forgot to put in a topic branch.  Since I
  didn't want to carry all of that tip timer stuff in powerpc -next, I
  setup a separate branch on top of Thomas tree with just that cpuidle
  driver in it, and Stephen has been carrying that in next separately
  for a while now.  I'll send a separate pull request for it.

  Additionally, two new pieces in this tree add users for a sysfs API
  that Tejun and Greg have been deprecating in drivers-core-next.
  Thankfully Greg reverted the patch that removes the old API so this
  merge can happen cleanly, but once merged, I will send a patch
  adjusting our new code to the new API so that Greg can send you the
  removal patch.

  Now as for the content of this branch, we have a lot of perf work for
  power8 new counters including support for our new "nest" counters
  (also called 24x7) under pHyp (not natively yet).

  We have new functionality when running under the OPAL firmware
  (non-virtualized or KVM host), such as access to the firmware error
  logs and service processor dumps, system parameters and sensors, along
  with a hwmon driver for the latter.

  There's also a bunch of bug fixes accross the board, some LE fixes,
  and a nice set of selftests for validating our various types of copy
  loops.

  On the Freescale side, we see mostly new chip/board revisions, some
  clock updates, better support for machine checks and debug exceptions,
  etc..."

Arnaud Ebalard 594fbe713b Add support for GMT G762/G763 PWM fan controllers
GMT G762/763 fan speed PWM controller is connected directly to a fan
and performs closed-loop or open-loop control of the fan speed. Two
modes - PWM or DC - are supported by the chip. Introduced driver
provides various knobs to control the operations of the chip (via
sysfs interface). Specific characteristics of the system can be passed
either using board init code or via DT. Documentation for both the
driver and DT bindings are also provided.

Linus Torvalds 151173e8ce Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core now
   automatically populates supplied_from hierarchy from the device tree.
   With these patches chargers and batteries can now lookup each other
   without the board files support shim. Rhyland Klein at NVIDIA did the
   work;
 
 - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the
   AB85xx core and depends on some recent changes to it, so that is why the
   driver comes through the battery tree. It has an appropriate ack from
   the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson
   and Hongbo Zhang at Linaro authored the driver;
 
 - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes
   touch mfd parts, but these were acked by the appropriate MFD maintainer
   (i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
   the submission process.
 
 Minor changes, but still worth mentioning:
 
 - Battery temperature reporting fix for Nokia N900 phones;
 - Versatile Express poweroff driver moved into drivers/power/reset/.
 - Tree-wise: use devm_kzalloc() where appropriate;
 - Tree-wise: dev_pm_ops cleanups/fixes.

Lars-Peter Clausen 51c2a4871c hwmon: (adt7410) Add support for the adt7310/adt7320
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map
layout is a bit different, i.e. the register addresses differ between the two
variants, but the bit layouts of the individual registers are identical. So both
chip variants can easily be supported by the same driver. The issue of non
matching register address layouts is solved by a simple look-up table which
translates the I2C addresses to the SPI addresses.

The patch moves the bulk of the adt7410 driver to a common module that will be
shared by the adt7410 and adt7310 drivers. This common module implements the
driver logic and uses a set of virtual functions to perform IO access. The
adt7410 and adt7310 driver modules provide proper implementations of these IO
accessor functions for I2C respective SPI.

Jonathan Cameron 51b53dc991 hwmon: Move the IIO client driver for hwmon out of staging
This driver uses channel maps, defined either through device tree
or platform data, to create a hwmon driver which acts as a client
for the underlying IIO device channels.  Thus a general purpose
IIO adc driver can be used to provide hardware monitoring using a subset
of its channels.

--
 The only non move changes here concern the description and changes to the
 dependencies to IIO explicit and hwmon implicit.

 I'm proposing moving this into hwmon on the basis of placing drivers
 based on what they provide rather than what their underlying hardware
 is.
