Greg Kroah-Hartman e5b9c05772 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.

Marcus Folkesson c76782d151 iio: adis16400: Set timestamp as the last element in chan_spec
This is necessary since timestamp is calculated as the last element
in iio_compute_scan_bytes().

Without this fix any userspace code reading the layout of the buffer via
sysfs will incorrectly interpret the data leading some nasty corruption.

Jonathan Cameron 3425c0f7ac iio:imu:adis16400 fix pressure channel scan type
A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel.  Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

Lars-Peter Clausen 76ada52f7f iio:adis16400: Add support for the adis16448
The adis16448 is more or less from the same family of devices as supported by
this driver. It features three acceleration channels, three angular velocity
channels, three magnetometer channels, one temperature channels and one
barometric pressure channel.

Lars-Peter Clausen 7ba8a04dcd iio:adis16400: Add support for the 52.85 Hz base sampling rate
The adis16400 and similar have two different base sampling rate available, from
which the actual sampling rate is derived. 1638 Hz and 52.85 Hz, switching to
the lower base sampling rate allows to support lower sampling rates.

This patch adds support for switching to the lower base sampling rate if the
requested sampling frequency is outside of the range which can be supported by
the higher base sampling rate.

The function which is used to read the current sampling rate already has support
for the lower sampling rate, so no changes are required there.
