2016-09-19staging: lustre: obd: add lnb_ prefix to members of struct niobuf_localJohn L. Hammond
Add the prefix lnb_ to the members of struct niobuf_local that do not already have it. Change the struct dentry *lnb_dentry member to void *lnb_data as it is not used to hold a pointer to struct dentry. Signed-off-by: John L.

2016-09-18iio: accel: kxsd9: Deploy system and runtime PMLinus Walleij
This deploys runtime and system PM in the KXSD9 driver: - Use the force_runtime_suspend/resume callbacks as system PM operations. - Add buffer prepare/unprepare callbacks to grab the runtime PM while we're using buffered reads and put get/put_autosuspend in these. - Insert get/put_autosuspend calls anywhere the IO is used from the raw read/write callbacks. - Move the fullscale setting to be cached in the state container so we can restore it properly when coming back from system/runtime suspend. - Set the autosuspend delay to two orders of magnitude that of the sensor start-up time (20ms) so we will autosuspend after 2s. - Register the callbacks in both the SPI and I2C subdrivers.

2016-09-18iio: accel: kxsd9: Replace "parent" with "dev"Linus Walleij
What is passed to the .probe() and .remove() functions is technically the parent of the created IIO device but it becomes a big confusion for the head to have it named like this since it is usually clear from context the "dev" refers to the physical device, and when next adding PM callbacks a clean "struct device *dev" pointer is passed to these and that makes it even more confused.

2016-09-18iio: accel: kxsd9: Add triggered buffer handlingLinus Walleij
As is custom with all modern sensors, add a clever burst mode that will just stream out values from the sensor and provide it to userspace to do the proper offsetting and scaling. This is the result when tested with an HRTimer trigger: $ generic_buffer -a -c 10 -n kxsd9 -t foo /sys/bus/iio/devices/iio:device1 foo 0.371318 0.718680 9.869872 1795.000000 97545896129 -0.586922 0.179670 9.378775 2398.000000 97555864721 -0.299450 0.179670 10.348992 2672.000000 97565874055 0.371318 0.335384 11.103606 2816.000000 97575883240 0.179670 0.574944 10.540640 2847.000000 97585862351 0.335384 0.754614 9.953718 2840.000000 97595872425 0.179670 0.754614 10.732288 2879.000000 97605882351 0.000000 0.754614 10.348992 2872.000000 97615891832 -0.730658 0.574944 9.570422 2831.000000 97625871536 0.000000 1.137910 10.732288 2872.000000 97635881610 Columns shown are x, y, z acceleration, so a positive acceleration of ~9.81 (shaky due to bad calibration) along the z axis. The fourth column is the AUX IN which is floating on this system, it seems to float up to the 2.85V VDD voltage. To be able to cleanup the triggered buffer, we need to add .remove() callbacks to the I2C and SPI subdrivers and call back into an exported .remove() callback in the core.

2016-09-18iio: accel: kxsd9: Fix up offset and scalingLinus Walleij
This fixes several errors in the offset and scaling of the raw values from the KXSD9 sensor: - The code did not convert the big endian value from the sensor into the endianness of the host CPU. Fix this with be16_to_cpu() on the raw obtained value. - The code did not regard the fact that only the upper 12 bits of the accelerometer values are valid. Shift these down four bits to yield the real raw value. - Further the sensor provides 2048 at zero g. This means that an offset of 2048 must be subtracted from the raw value before scaling. This was not taken into account by the driver, yielding a weird value. Fix this by providing this offset in sysfs. To house the scaling code better, the value reading code was factored into the raw reading function. This proper scaling and offseting is necessary to get proper values out of triggered buffer by offsetting, shifting and scaling them.

We export the common probe and add a local header file for the functionality shared between the main driver and the transport driver. We make the SPI transport the default for the driver if SPI is available and the KXSD9 driver was selected, so the oldconfig upgrade path will be clear.
