b79013b244 Staging driver patches for 4.1-rc1
Here's the big staging driver patchset for 4.1-rc1.
 
 There's a lot of patches here, the Outreachy application period happened
 during this development cycle, so that means that there was a lot of
 cleanup patches accepted.  Other than the normal coding style and sparse
 fixes here, there are some driver updates and work toward making some of
 the drivers into "mergable" shape (like the Unisys drivers.)
 
 All of these have been in linux-next for a while.

dc5f2c5f6a First set of new drivers, cleanups and functionality for IIO in the 4.1 cycle.
New drivers
 * CM3323 color sensor.
 * MS5611 pressure and temperature sensor.
 
 New functionality
 * mup6050 - create mux clients for devices described via ACPI. The reasoning
      and approach taken in this patch are complex.  Basically there is no
      otherway of finding out what is there than by some esoteric look ups in
      the ACPI data.
 * cm3232 - PM support
 * itg3200 - suspend/resume support
 * mcp320x - add more ADCs to the kconfig to reflect what the driver supports
      (this patch and the bindings got left behind when the support was added
       a while back).
 
 Docs / utils
 * ti-adc128s052 - DT bindings.
 * mcp3422 - DT bindings.
 * mcp320x - DT bindings
 * ABI docs for event threshold scale attributes, in_magn_offset, proximity
   scan_element and thresh falling/rising values for accelerometers.  All
   elements long in use that have slipped by being explicitly documented.
 * Tidy up the tools previously in drivers/staging/iio/Documentation and move
   them out to /tools/iio. Yet another move that should have happened long ago.
   This time Roberta Dobrescu did the leg work.  Thanks!
 
 Core Cleanups
 * Export userspace IIO headers.  We should have done the appropriate header
   splitting a long time ago. Thanks to Daniel for sorting this out.
 
 * Refactor the registring of attributes for buffers to move all non-custom
   ones to a vector allowing easier additions to the current set in the future.
 
 Driver Cleanups
 * gpiod related cleanups.  Make use of the additional parameter to specify
   	initial direciton to avoid extra code.
 * bmc150 - Various refactorings to reduce code repitition and prepare for
            hardware buffer support.  Some of these cleanups are good even
 	   without the new functionality.
 * kmx61 - direct use of index to an array avoiding a structure element which
           was always the index to an element in an array of that structure.
 * vf610 - avoid incorrect type for return from wait_for_completion_timeout.
 * gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
 * ade7754 - improve error handling including suppressing some build warnings.
 * ade7759 - improve error handling including suppressing some build warnings.
 * hmc5843 - Long line and indentation fixes. Also some constifying of various
       constant data.
 * ade7854 - 80+ character line splitting.
 * ad2s1210 - fix wrong printf format string.
 * mxs-lradc - fix wrong printf format string.
 * ade7954-i2c - code alignment fixes and other trivial but worthwhile bits.
 * periodic rtc trigger - make the frequency type an unsigned int as it
   is always treated as such.
 * jsa1212 - constify struct regmap_config as it is constant.
 * ad7793 - typo in the MODULE_DESCRIPTION
 * mma9551 - check gpiod_to_irq errors.  Note that this doesn't actually cause
     any trouble but is worth tidying up as obviously incorrect.
 * mlx90614 - refactor the register symbols to make it clear which reads are to
     RAM not PROM.

 things in here, adding up to lots of overall cleanups.  The IIO driver
 updates are also in here as they cross the staging tree boundry a lot.
 I2O has moved into staging as well, as a plan to drop it from the tree
 eventually as that's a dead subsystem.

Here is the big staging patch set for 3.18-rc1.
 
 Once again, we are deleting more code than we added, with something like
 150000 lines deleted overall.  Some of this is due to drivers being
 added to the networking tree, so the old versions are removed here, but
 even then, the overall difference is quite good.
 
 Other than driver deletions, lots and lots and lots of minor cleanups
 all over the place.  Full details are in the shortlog below.

4c21bbb475 iio: adc: rockchip_saradc: add support for rk3066-tsadc variant
Older Rockchip SoCs, at least the rk3066, used a slightly modified saradc
for temperature measurements. This so called tsadc does not contain any
active parts like temperature interrupts and only supports polling the
current temperature. The returned voltage can then be converted by a
suitable thermal driver to and actual temperature and used for thermal
handling.

f83ccb9358 ARM: SoC: device tree changes
A large part of the arm-soc patches are nowadays DT changes, adding support
 for new SoCs, boards and devices without changing kernel source. The plan
 is still to move the devicetree files out of the kernel tree and reduce
 the amount of churn going on here, but we keep finding reasons to delay
 doing that.
 
 Changes are really all over the place, with little sticking out particularly.
 We have contributions from a total of 116 people in this branch.
 
 Unfortunately, the size of this branch also causes a significant number
 of conflicts at the moment, typically when subsystem maintainers merge
 patches that change the driver at the same time as the dts files. In
 most cases this could be avoided because the dts changes are supposed
 to be compatible in both ways, and we are asking everyone to send ARM
 dts changes through our tree only.

588858c4df devicetree: Add Xilinx XADC binding documentation
The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.

Each of them needs:
	* A address range where the registers are mapped
	* An interrupt number for the device interrupt
	* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
	  clock, for the AXI softmacro it is the AXI bus interface clock.

Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.
