2017-01-12staging: iio: ad7606: fix improper setting of oversampling pinsEva Rachel Retuya
commit b321a38d2407c7e425c54bc09be909a34e49f740 upstream. The oversampling ratio is controlled using the oversampling pins, OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control bit. The gpio connected to the OS2 pin is not being set correctly, only OS0 and OS1 pins are being set. Fix the typo to allow proper control of the oversampling pins.

2016-11-18staging: iio: ad5933: avoid uninitialized variable in error caseArnd Bergmann
commit 34eee70a7b82b09dbda4cb453e0e21d460dae226 upstream. The ad5933_i2c_read function returns an error code to indicate whether it could read data or not. However ad5933_work() ignores this return code and just accesses the data unconditionally, which gets detected by gcc as a possible bug: drivers/staging/iio/impedance-analyzer/ad5933.c: In function 'ad5933_work': drivers/staging/iio/impedance-analyzer/ad5933.c:649:16: warning: 'status' may be used uninitialized in this function [-Wmaybe-uninitialized] This adds minimal error handling so we only evaluate the data if it was correctly read.

2015-11-21staging: iio: dummy: complete IIO events delivery to userspaceIoana Ciornei
Starting with commit fd2bb310ca (Staging: iio: Move evgen interrupt generation to irq_work) event processing is handled by calling both the top half and the threaded part properly simulating real hardware interrupts making use of threaded interrupts. This way the processing is split in 2 parts: * the IRQ handler that runs in IRQ context and only saves the event timestamp * the threaded handler that runs in process context, reads the events and pushes the in the userspace. If the IRQ handler returns IRQ_HANDLED the threaded handler is not even being called since the interrupt is considered to be processed. Because the iio dummy driver processes the events in the threaded handler the IRQ handler must return IRQ_WAKE_THREAD so that the threaded part would be awakened and called.

ssh://ra.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First set of IIO fixes for the 4.4 cycle. This set does not include those for issues introduced during the merge window. Fixes of those will follow in a future series. * ad5064 - Make sure the local i2c_write returns 0 on success rather than the number of bytes transfered. Otherwise we report an error on all writes. - Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on these parts. * ad7793 - The product ID on the datasheet is wrong. Fix it in the driver. * IIO_DUMMY_EVGEN - select IRQ_WORK as a dependency. * lpc32xx - make sure clock is prepared before enabling. * si7020 - data byte order was reversed. Fix it. * vf610 - Internal temperature calculation was wrong if a different reference voltage was used. Now use a linear interpolation function to make it work over the full range. - Fix a division by zero in the case of a device tree property not being present (same issue two fixes). * xilinx XADC - VREFN scale was wrong - fix it.

Note that the htu21 has a driver in hwmon, but the view from that side was that, given the range of devices the same silicon turns up in are not all typical hwmon material, that driver would be deprecated in favour of this new support. - ms8607 temperature, pressure and humidty sensor - ms5637 temperature and pressure sensor - htu21 temperature and humidity sensor - tsys02d temperature sensor - tsys01 temperature sensor Cleanups * tree wide. - squish cases where irq 0 is still considered valid. * apds9960 - sparse endian warning cleanups by making endianness explicit. * ad5504 - leave group naming to the core. * ad7746 - cleanup comment style. - drop an unnecessary bit of dev_info - add some appropriate uses of the BIT macro. * ad799x - leave group naming to the core. * hdc100x - introduced this cycle,. - fix a wrong offset value. * lidar - add missing MODULE_DEVICE_TABLE for dt. * max1363 - leave sysfs group naming to the core. * m62332 got the Harmut treatment and as ever he found a 'few' bits the rest of us had missed! - Share scale and offset attributes across channels. - Shutdown the device on driver remove - Use ARRAY_SIZE rather than a hard coded count for channels. - Return more directly in the write_raw callback dropping a local variable along the way. - a few style issues - move to reading the regulator voltage for each use allowing for dynamic regulators. This is a common feature across drivers so we might end up with more fixes throughout the tree for this. * mlx96014 - introduced this cycle. - fixed up a spot of error handling. * vz89x - introduced this cycle. - work around a hardware quirk.
