Merge tag 'iio-for-3.15a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes: First set of new drivers and cleanups for IIO in the 3.15 cycle. New drivers: * si7005 relative humidity and temperature sensor * Lite-on ltr501 ambient light and proximity sensor Cleanups * Clean up some dead comments in max1363 * Drop some obsolete variables in adjd_s311 and tcs3472 left over from the introduction of iio_push_to_buffers_with_timestamp. * Drop some unneeded linux/init.h includes * Squish a sparse warning in mpl3115 by correctly specifying a be32 variable. * A number of cleanups and fixes for sca3000 * Drop an unneed checks in mxs-lradc, ad7303 and adis16400. * Drop a platform_set_drvdata in viperboard after the only use of it was removed during a devm conversion. * Add a missing device name for ak8975 to comply with the ABI. * Put mpu6050 into the IMU menu as it slipped out into the main menu. * Fix a typo and some comment formatting in mpu6050. * Document at91 ADC clock properties.
