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.

2014-02-08iio: ak8975: Fix calculation formula for convert micro tesla to gauss unitBeomho Seo
This effects the reported scale of the raw values, and thus userspace applications that use this value. One micro tesla equal 0.01 gauss. So I have fixed calculation formula And add RAW_TO_GAUSS macro. ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO. As a result, read_raw call back function return accurate scale value.

We can't store the trigger instance created by iio_trigger_alloc, in trig field of iio_device structure. This needs to be stored in the driver private data.

2013-10-20iio: Correct description how to convert microtesla to gaussPeter Meerwald
this just fixes the comment; however, I'm not sure if the driver reports measurements correctly; the raw values are 0.3 uT / LSB; IIO is supposed to report magnetic fields in Gauss, so the scale should be around 1/300 (ignoring ASA) -- but value and scale are returned as VAL_INT Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
