git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First set of IIO fixes for the 4.2 cycle. * Fix a regression in hid sensors suspend time as a result of adding runtime pm. The normal flow of waking up devices in order to go into suspend (given the devices are normally suspended when not reading) to a regression in suspend time on some laptops (reports of an additional 8 seconds). Fix this by checking to see if a user action resulting in the wake up, and make it a null operation if it didn't. Note that for hid sensors, there is nothing useful to be done when moving into a full suspend from a runtime suspend so they might as well be left alone. * rochip_saradc: fix some missing MODULE_* data including the licence so that the driver does not taint the kernel incorrectly and can build as a module. * twl4030 - mark irq as oneshot as it always should have been. * inv-mpu - write formats for attributes not specified, leading to miss interpretation of the gyro scale channel when written. * Proximity ABI clarification. This had snuck through as a mess. Some drivers thought proximity went in one direction, some the other. We went with the most common option, documented it and fixed up the drivers going the other way. Fix for sx9500 included in this set. * ad624r - fix a wrong shift in the output data. * at91_adc - remove a false limit on the value of the STARTUP register applied by too small a type for the device tree parameter. * cm3323 - clear the bits when setting the integration time (otherwise we can only ever set more bits in the relevant field). * bmc150-accel - multiple triggers are registered, but on error were not being unwound in the opposite order leading to removal of triggers that had not yet successfully been registered (count down instead of up when unwinding). * tcs3414 - ensure right part of val / val2 pair read so that the integration time is not always 0. * cc10001_adc - bug in kconfig dependency. Use of OR when AND was intended.
2015-07-11iio: Drop owner assignment from i2c_driverKrzysztof Kozlowski

2015-06-21iio: DAC: ad5624r_spi: fix bit shift of output data valueJM Friedt
The value sent on the SPI bus is shifted by an erroneous number of bits. The shift value was already computed in the iio_chan_spec structure and hence subtracting this argument to 16 yields an erroneous data position in the SPI stream.
