git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: Second set of IIO fixes for the 4.6 cycle. This lot are either dependent on patches from the merge window or just came in recently enough that they ended up in this tree. * core - The watermark for the buffers was given a value that meant that it was impossible to actually set the watermark to anything sensible. * at91_adc - Fix a build config dependency on HAS_IOMEM * bmc150 - Fix wrong output on big endian systems * bmg160 - Fix wrong output on big endian systems - Fix an issue in which the regmap return value was stored to the buffer rather than the value actually being read in a bulk read. * inv_mpu6050 - Fix an indirect build config dependency on HAS_IOMEM * max30100 - Fix an error in fifo check condition that leads to a double read of the final reading. * st_magn - Make sure ST_MAGN_TRIGGER_SET_STATE is always defined to avoid a build error for relatively obscure config combinations.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into usb-linus Jonathan writes: First round of IIO fixes for the 4.6 cycle. Again I've ended up with two early fix sets, depending on whether they are dependent on elements of the merge window or simply came in after I had patches with that dependency already, vs older fixes that were just too late for the last cycle. This first set is for the older ones. - max1353 * Add a missing adc to max1363_id - the driver has supported the max11644-11647 for a while, but as they weren't in the id table there was no way of actually initializing it. * Fix a wrong reference voltage for the above models. Given you couldn't initialize the driver for these parts without patching, no one noticed that the reference voltage used in computing the scaling was wrong. - apds9960 * The fifo last enelement was read twice (and hence pushed out twice) due to a small logic bug.
2016-04-03iio: gyro: bmg160: fix buffer read valuesIrina Tirdea
When reading gyroscope axes using iio buffers, the values returned are always 0. In the interrupt handler, the return value of the read operation is returned to the user instead of the value read. Return the value read to the user. This is also fixed in commit 82d8e5da1a33 ("iio: accel: bmg160: optimize transfers in trigger handler").

2016-04-03iio: gyro: bmg160: fix endianness when reading axesIrina Tirdea
For big endian platforms, reading the axes will return invalid values. The device stores each axis value in a 16 bit little endian register. The driver uses regmap_read_bulk to get the axis value, resulting in a 16 bit little endian value. This needs to be converted to cpu endianness to work on big endian platforms. Fix endianness for big endian platforms by converting the values for the axes read from little endian to cpu. This is also partially fixed in commit 82d8e5da1a33 ("iio: accel: bmg160: optimize transfers in trigger handler").

2016-04-03iio: st_magn: always define ST_MAGN_TRIGGER_SET_STATEArnd Bergmann
When CONFIG_IIO_TRIGGER is enabled but CONFIG_IIO_BUFFER is not, we get a build error in the st_magn driver: drivers/iio/magnetometer/st_magn_core.c:573:23: error: 'ST_MAGN_TRIGGER_SET_STATE' undeclared here (not in a function) .set_trigger_state = ST_MAGN_TRIGGER_SET_STATE, ^~~~~~~~~~~~~~~~~~~~~~~~~ Apparently, this ST_MAGN_TRIGGER_SET_STATE macro was meant to be set to NULL when the definition is not available because st_magn_buffer.c is not compiled, but the alternative definition was not included in the original patch.

2016-03-28iio: fix config watermark initial valueIrina Tirdea
config structure is set to 0 when updating the buffers, so by default config->watermark will be 0. When computing the minimum between config->watermark and the buffer->watermark or insert_buffer-watermark, this will always be 0 regardless of the value set by the user for the buffer. Set as initial value for config->watermark the maximum allowed value so that the minimum value will always be set from one of the buffers.

The long term intention is to probably remove the hwmon driver but for now we just have guards in place to ensure this driver is not built if that one is enabled. * TI afe4403 - new driver for this heart rate monitor / pulse oximeter front end chip. * TI afe4404 - new driver for this heart rate monitor / pulse oximeter front end chip. Staging Graduations * mxs-lradc - A combined general purpose and touch screen (input) device driver. Originally held in staging to allow reworking into and MFD but as that wasn't happening and isn't an absolute requirement we are moving it out of staging. Driver new features * ms5611 - triggered buffer support - IIO_CHAN_INFO_SCALE to aid the triggered buffer support. Driver cleanups / reworks / fixes * ad5064 - Use an enum for the register map layout to allow support of additional chips (precursor to the new support listed above). - Structural driver changes to allow support of the slightly different handling for the ltc parts above. * ad5933 - drop an exceptional & unnecessary for a function pointer. * ad7606 - Cleanup the repeated copies of pm ops. - consolidate the various channels specs via a sport of rearranging so only one version is needed. * atlas ph sensor - add select IRQ_WORK * hmc8543 (soon to move out of staging) - Comment style fixes - functionality of suspend and resume was swapped. * spear-adc - use devm_clk_dev instead of managing the clk lifetime by hand. Core * Use new dmaengine_terminate_sync call to avoid a theoretical race. * Fix docs for mlock in struct iio_dev as it is correctly taken in some drivers (docs used to say for core only). * Add a helper function for calculating the scan index storage size within the core cutting out some cut and paste versions of the same code.

2016-02-13iio: Add IIO support for the DAC on the Apex Embedded Systems STX104William Breathitt Gray
The Apex Embedded Systems STX104 is a 16-channel 16-bit analog input and 2-channel 16-bit analog output PC/104 card. The STX104 incorporates a large one mega-sample FIFO. This driver provides IIO support for the 2-channel DAC on the STX104. The base port addresses for the devices may be configured via the "base" module parameter array.
