git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: 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.
2016-04-19iio: tools: generic_buffer: auto-enable channelsLinus Walleij
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.

2016-04-07tools/power turbostat: work around RC6 counter wrapLen Brown
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. Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Rafael J.

Used in ad7192 driver. * ak8975 - power regulator support. * at91-sama5d2 - differential channel support. * mma8452 - runtime pm support - drop device specific autosleep and use the runtime pm one instead. * ms5611 - DT bindings - oversampling ratio support Cleanups and minor fixes * MAINTAINERS - Peter got married - hence name change! * Documentation - Fix a typo in in_proximity_raw description. - Add some missing docs for iio_buffer_access_funcs. * Tools - update iio_event_monitor names to match new stuff. - make generic_buffer look for triggers ending in -trigger as we let these in for a number of drivers a long time back and now it is a fairly common option. Drivers * staging wide - convert bare unsigned usage to unsigned int to comply with coding style. * non staging wide: - since boiler plate gpio handling of interrupts has been moved into the ACPI core we don't need to include gpio/consumer.h in a load of drivers so drop it. * ad7606 - fix an endian casting sparse warning. * ak8975 - fix a possible unitialized warning from gcc. - drop and unused field left over from earlier cleanups - fix a missing regulator_disable on exit. * at91-sama5d2 - typo and indentation - missing IOMEM dependency. - cleanup mode register usage by avoidling erasing whole thing when changing the sampling frequency. * bmc150 - 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 - replace deprecated flush_scheduled_work

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.

samples In 473398a21d28 ("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.

2016-03-24perf tests: Fix tarpkg build test error output redirectionArnaldo Carvalho de Melo
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.

2016-03-23tools lib traceevent: Remove redundant CPU outputSteven Rostedt
Commit a6745330789f ("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.
