5a45e01d41 2nd set of new device support, features and cleanup for IIO in the 4.7 cycle.
Bit of a bumper set for new drivers but plenty of other stuff here as well!
 
 New device support
 * ad5592R ADC/DAC
   - new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
 * Aosong am2315 relative humidity
   - new driver with triggered buffer support in follow up patch.
 * bmi160 imu
   - new driver
 * bmp280
   - bmp180 support - note there is support in the misc/bmp085 driver. Intent
     is to remove that driver long term.
 * invensense mpu6050
   - cleanup leading to explicit support of mpu9150 with a good few cleanups
     along the way.
 * Hope RF hp03 pressure and temperature sensor.
   - new driver
 * maxim DS1803 potentiometer
   - new driver
 * maxim max44000 light and proximity sensor
   - new driver built in a series of steps to support pretty much everything.
 * ROHM BH1780 light sensor
   - new driver. There is an existing driver in misc that this is pretty much
     intended to replace.  The discussion on whether to support the non standard
     interface of that driver is some way is continuing.
 * st-gyro
   - lsm9ds0-gyro.  The accel/magn side of this will take a while longer as
     extensions to the st library are needed for cases where two types of sensor
     share a single i2c address.
 * ti-adc081c
   - support the adc101c and adc121c
 * Vishay VEML6070 UV sensor
   - new driver.
 
 New features
 * core
   - devm_ APIs for channel_get and channel_get_all.  The first user of these
     is the generic ADC based thermal driver.  As it is going through the
     thermal tree these will be picked up as a patch to that next cycle as that
     is how the author preferred to do it.
   - mounting matrix support.  This new core support allows devices to provide
     to userspace (typically from the device tree) allowing compensation for how
     the sensor is mounted on the device.  First examples are on UAVs but it
     has a more mundane use on typical phone where the chip may be on the front
     or the back of the circuit board and soldered at any angle. Includes
     support for this ABI in ak8975 (which has an older interface, now
     deprecated) and mpu6050.
 * tools
   - add a -a option to enable all available channels in generic_buffer sample.
     Makes it somewhat easier to use.
 * adis library and drivers
   - support manual self test flag clearing.  This has technically been broken
     for a very long time - result is an offset on readings as the applied field
     is on all the time.
 * ak8975
   - triggered buffer support
 * bmc150
   - spi support (including splitting the driver into core and i2c parts)
 * bmp280
   - oversampling support.
 * dht11
   - improved logging - useful to debug timing issues on this quirky device.
 * st-sensors
   - read each channel invidivually as not all support the optimization of
   reading in bulk.  This is technically a fix, but will need to be backported
   if desired.
   - support open drain and shared interrupts.
 * ti-adc081c
   - triggered buffer support.
 
 Cleanups
 * inkern
   - white space fix.
 * ad7606
   - use the iio_device_claim_direct_mode call rather than open coding equiv.
 * ad799x
   - white space fix.
 * ad9523
   - unsigned -> unsigned int
 * apds9660
   - brace location tidying up.
   - silence an uninitialized variable warning.
 * ak8975
   - else and brace on same line fix.
 * at91_adc
   - white space fixes.
 * bmc150
   - use regmap stored copy of the device pointer rather than having an
     additional copy.
 * bmg160
   - use regmap stored copy of the device pointer rather than having an
     additional copy.
 * hid-sensors
   - white space fixes.
 * mcp3422
   - white space fix.
 * mma7455
   - use regmap to retrieve the device struct rather than carrying another copy
     in the private data.
 * ms_sensors
   - white space fix.
 * mxs-lradc
   - move current bindings out of staging - some will be shortly deprecated but
     the reality is that we have device trees out there using them so they will
     need to be supported for some time.  They accidentally got left behind
     when the driver graduated from staging.
   - white space cleanup.
   - set INPUT_PROP_DIRECT.
   - move ts config into a better function.
   - move the STMP reset out of the ADC init.
 * vf610_adc
   - case label indenting fix.

5f991a921a iio: tools: generic_buffer: auto-enable channels
If no channels are enabled when we run generic_buffer on a
device, add a command-line option to just enable all of them,
run the sampling and disable them all again afterwards.

This is extremely useful when I'm low-level testing my
sensors with interrupts and triggers, sample session:

9185e988e9 tools/power turbostat: work around RC6 counter wrap
Sometimes the rc6 sysfs counter spontaneously resets,
causing turbostat prints a very large number
as it tries to calcuate % = 100 * (old - new) / interval

When we see (old > new), print ***.**% instead
of a bogus huge number.

Note that this detection is not fool-proof, as the counter
could reset several times and still result in new > old.

    ACPI core we don't need to include gpio/consumer.h in a load of drivers so
    drop it.

   - use the core demux and available_scan_masks to simplify buffer handling
   - optimize the transfers in the trigger handler now we have a magic function
   to emulate bulk reads (under circumstances met here).  This matters with some
   rather dumb i2c adapters in particular.
   - use a single regmap_conf for all bus types as they were all the same.
 * bmg160
   - use the core demux and available_scan_masks to simplify the buffer handling
   - optimize the transfers in the trigger handler now we have a magic funciton
   to emulate bulk rads (under circumstances met here).
   - drop gpio interrupt probing from the driver (ACPI) as now handled by the
   ACPI core.
 * ina2xx-adc
   - update the CALIB register when RShunt changes.
   - fix scale for VShunt - in reality this error canceled out when used.
 * isl29028
   - use regmap to retrieve the struct device instead of carrying a second
   copy of it around.
 * kxcjk-1013
   - use core demux
   - optimize i2c transfers in the trigger handler.
 * mcp4531
   - refactor to use a pointer to access model parameters instead of indexing
     into the array each time.
 * mma8452
   - style fixes
   - avoid swtiching to active whenever the config changes
   - add missin i2c_device_id for mma8451
 * mpu6050
   - fix possible NULL dereference.
   - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
 * ms5611
   - fix a missing regulator_disable that left the regulator on during removal.
 * mxc4005
   - drop gpio interrupt handling for ACPI case from driver as the core now
   handles this case.
 * st-sensors
   - note that there are only ever a maximum of 3 axis on current st-sensors
   so just allocate a fixed sized buffer big enough for that.
 * tpl0102
   - change the i2c_check_functionality condition to bring it inline with other
     IIO users as EOPNOTSUPP.
 * tsl2563

9f56c092b9 perf jit: genelf makes assumptions about endian
Commit 9b07e27f88 ("perf inject: Add jitdump mmap injection support")
incorrectly assumed that PowerPC is big endian only.

Simplify things by consolidating the define of GEN_ELF_ENDIAN and checking
for __BYTE_ORDER == __BIG_ENDIAN.

The PowerPC checks were also incorrect, they do not match what gcc
emits. We should first look for __powerpc64__, then __powerpc__.

9098903555 perf hists: Fix determination of a callchain node's childlessness
The 4b3a321223 ("perf hists browser: Support flat callchains") commit
over-aggressively tried to optimize callchain_node__init_have_children().

That lead to --tui mode not allowing to expand call chain elements if a
call chain element had only one parent. That's why --inverted callgraphs
looked halfway sane, but plain ones didn't.

Revert that individual optimization, it wasn't really related to the
rest of the commit.

a189c017de tools/lib/lockdep: Fix unsupported 'basename -s' in run_tests.sh
Here on Ubuntu/precise I have GNU/coreutils v8.13 installed
where 'basename -s' is not supported.

The result is that run_tests.sh is not done properly.

How to reproduce:

  $ cd $BUILD_DIR
  $ LC_ALL=C make -C tools/ liblockdep
  $ cd tools/lib/lockdep/

    $ LC_ALL=C ./run_tests.sh
  basename: invalid option -- 's'
  Try `basename --help' for more information.
  ... timeout: failed to run command `./tests/': Permission denied
  FAILED!
  rm: cannot remove `tests/': Is a directory

Due to unsupported basename the tests programs are not generated
and cannot be removed.

Fix this by doing a compatible basename invocation and check for
the existence of generated tests programs.

For more details see this LKML thread:

3ea223adcb perf tools: Add missing initialization of perf_sample.cpumode in synthesized samples
In 473398a21d ("perf tools: Add cpumode to struct perf_sample"), I
missed some places where perf_sample fields are directly initialized in
addition to what is done in perf_evsel__parse_sample(), namely when
synthesizing PERF_RECORD_{MMAP*,COMM,FORK,EXIT} for pre-existing threads
and also in intel_pt and intel_bts when synthesizing events from
processor trace, the jitdump code also was affected, fix it.

The problem was noticed with running:

  # perf record -e intel_pt//u true
  # perf script

Where the samples wouldn't get resolved because perf_sample.cpumode
would be left as zero, i.e. PERF_RECORD_MISC_CPUMODE_UNKNOWN, not
resolving as kernel, hypervisor or user cpu modes.

6a1a77baa7 perf bench: Fix detached tarball building due to missing 'perf bench memcpy' headers
A change on kernel files included by the 'perf bench memcpy' code grew some new
include deps, breaking the detached tarball build:

  $ make -C tools/perf build-test
  make: Entering directory '/home/acme/git/linux/tools/perf'
  - tarpkg: ./tests/perf-targz-src-pkg .
  tests/make:302: recipe for target 'tarpkg' failed
  make[1]: *** [tarpkg] Error 2
  Makefile:102: recipe for target 'build-test' failed
  make: *** [build-test] Error 2
  make: Leaving directory '/home/acme/git/linux/tools/perf'
  $ cat tools/perf/tarpkg
  ./tests/perf-targz-src-pkg .
    PERF_VERSION = 4.5.g05f5ec
    PERF_VERSION = 4.5.g05f5ec
  In file included from bench/mem-memcpy-x86-64-asm.S:9:0:
  bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory
  compilation terminated.
  mv: cannot stat ‘bench/.mem-memcpy-x86-64-asm.o.tmp’: No such file or directory
  make[5]: *** [bench/mem-memcpy-x86-64-asm.o] Error 1

  make[4]: *** Waiting for unfinished jobs....
  make[3]: *** [perf-in.o] Error 2
  make[3]: *** Waiting for unfinished jobs....
  make[2]: *** [all] Error 2
  $

Add arch/*/include/asm/*features.h to tools/perf/MANIFEST so that we can
continue to use detached tarballs to build perf.

Now it builds ok, doing it manually:

  $ make help | grep perf

  $ ls -la perf-4.5.0.tar
  ls: cannot access perf-4.5.0.tar: No such file or directory
  $ make perf-tar-src-pkg

  $ cd perf-4.5.0/tools/perf
  $ make > /dev/null

  $ ls -la perf

cde88355f2 perf tests: Fix tarpkg build test error output redirection
So we need to trow away just stdout, leaving stderr to be caught by
the build tests infrastructure, so that we can see what went wrong
when the tarpkg build test fails:

  $ make -C tools/perf build-test
  make: Entering directory '/home/acme/git/linux/tools/perf'
  - tarpkg: ./tests/perf-targz-src-pkg .
  tests/make:302: recipe for target 'tarpkg' failed
  make[1]: *** [tarpkg] Error 2
  Makefile:102: recipe for target 'build-test' failed
  make: *** [build-test] Error 2
  make: Leaving directory '/home/acme/git/linux/tools/perf'
  $ cat tools/perf/tarpkg
  ./tests/perf-targz-src-pkg .
    PERF_VERSION = 4.5.g05f5ec
    PERF_VERSION = 4.5.g05f5ec
  In file included from bench/mem-memcpy-x86-64-asm.S:9:0:
  bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory
  compilation terminated.
  mv: cannot stat ‘bench/.mem-memcpy-x86-64-asm.o.tmp’: No such file or directory
  make[5]: *** [bench/mem-memcpy-x86-64-asm.o] Error 1
  make[5]: *** Waiting for unfinished jobs....
  make[4]: *** [bench] Error 2
  make[4]: *** Waiting for unfinished jobs....
  make[3]: *** [perf-in.o] Error 2
  make[3]: *** Waiting for unfinished jobs....
  make[2]: *** [all] Error 2
  $

So the test flow is:

1. Run: 'make -C tools/perf build-test'

2. One of its tests failed, in this case, the 'tarpkg' one

3. Look at what went wrong, by looking at the output of that test, in
   tools/perf/tarpkg

Admittedly, this should be shortcircuited to showing what went wrong directly
from the 'make build-test' step, but lets first fix this tarpkg one and the
problem it spotted, which should be fixed by adding some extra file to the
tools/perf/MANIFEST so that detached tarballs continue being self contained and
build successfully.

4f3c887688 tools lib traceevent: Remove redundant CPU output
Commit a674533078 ("tools lib traceevent: Split pevent_print_event()
into specific functionality functions") broke apart the function
pevent_print_event() into three functions.

The first function prints the comm, pid and CPU, the second prints the
timestamp.

But that commit added the printing of the CPU in the timestamp function,
which now causes pevent_print_event() to duplicate the CPU output.

Remove the redundant printing of the record's CPU from the timestamp
function.

3c52b658b8 perf bench numa: Fix assertion for nodes bitfield
Comparing bits and bytes in numa benchmark assertion

I hit the issue on two socket Power8 machine presenting its numa nodes
as 0,1,16,17 (according to numactl). Therefore I got error (and hang of
parent process):

    perf: bench/numa.c:296: bind_to_memnode: Assertion `!(g->p.nr_nodes > (int)sizeof(nodemask))' failed.

This is obviously false positive. We can fit all the 18 nodes into
bitfield of 8 bytes (long on 64b architecture).
