Greg Kroah-Hartman 1c46ae0af6 Second set of new device support, features and cleanup for the 4.3 cycle. 
Take 2 also includes a fix set that was too late for the 4.2 cycle.
 
 As we had a lot of tools and docs work in this set, I have broken those
 out into their own categories in this description.
 
 Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
 * Poll functions for both event chardev and the buffer one were returning
   negative error codes (via a positive value).
 * A recent change to lsiio adding some error handling that was wrong and
   stopped the tool working.
 * bmg160 was missing some dependencies in Kconfig
 * berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
 
 New device support
 * TI opt3001 light sensor
 * TXC PA12 ALS and proximity sensor.
 * mcp3301 ADC support (in mcp320x driver)
 * ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
   common support to allow different WHOAMI register addresses, devices with
   fixed scale and allow interrupt equiped magnetometers).
 * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
 * ADIS16266 gyro (in the adis16260 driver)
 * ADIS16137 gyro (in the adis16136 driver)
 
 New functionality
 * mmc35240 DT bindings.
 * Inverse unit conversion macros to aid handing of values written to sysfs
   attributes.
 
 Core cleanup
 * Forward declaration of struct iio_trigger to avoid a compile warning.
 
 Driver cleanup / fixes
 * mxs-lradc
   - Clarify which parts are supported.
   - Fix spelling erorrs.
   - Missing/extra includes
   - reorder includes
   - add datasheet name listings for all usable channels (to allow them
     to be bound by name from consumer drivers)
 * acpi-als - add some function prefixes as per general iio style.
 * bmc150_magn - replace a magic value with the existing define.
 * vf610 - determine possible sample frequencies taking into account the
   electrical characteristics (defining a minimum sample time)
 * dht11
   - whitespace
   - additional docs
   - avoid mulitple assignments in one line
   - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
     previously used for timing.
 * Fix all drivers that consider 0 a valid IRQ for historical reasons.
 * Export I2C module alias info where previously missing (to allow autoprobing)
 * Export OF module alias info where previously missing.
 * mmc35240 - switch some variables into arrays to improve readability.
 * mlx90614 - define some magic numbers for readability.
 * bmc150_magn
   - expand area locked by a mutex to cover all the use of the
     data->buffer.
   - use descriptive naming for a mask instead of a magic value.
 * berin2-adc
   - pass up an error code rather that a generic error
   - constify the iio_chan_spec
   - some other little tidy ups.
 * stk8312
   - fix a dependency on triggered buffers in kconfig
   - add a check for invalid attribute values
   - improve error handling by returning error codes where possible and
     return immediately where relevant
   - rework macro defs to use GENMASK etc
   - change some variable types to reduce unnecessary casting
   - clean up code style
   - drop a local buffer copy for bulk reads and use the one in data->buffer
      instead.
 * adis16400 - the adis16448 gyroscope scale was wrong.
 * adis16480 - some more wrong scales for various parts.
 * adis16300 - has an undocumented product id and serial number registers so
   use them.
 * iio_simple_dummy - fix some wrong code indentation.
 * bmc150-accel - use the chip ID to detect the chip present rather than
   verifying the expected part was there.  This was in response to a wrong
   ACPI entry on the WinBook TW100.
 * mma8452
   - fix _get_hp_filter_index
   - drop a double include
   - pass up an error code rather than rewriting it
   - range check input values to attribute writes
   - register defs tidy up using GENMASK and reordering them to be easier to
     follow.
   - various coding style cleanups
   - put the Kconfig entry in the write place (alphabetically).
 
 Tools related
 * Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
   use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
   them in the middle of normal output.
 * Fix tools to allow that scale and offset attributes are optional.
 * More tools fixes including allowing true 32bit data (previously an overflow
   prevented more than 31bits)
 * Drop a stray header guard that ended up in a c file.
 * Make calc_digits static as it isn't exported or in the header.
 * Set ci_array pointer to NULL after free as a protection against non safe
   usage of the tools core code.  Also convert a double pointer to a single
   one as the extra level of indirection was unnecessary.
 
 Docs
 * DocBook introduction by Daniel Baluta.  Glad we are beginning to
   draw together some more introductory docs to suplement the various
   tools / examples.
 * Drop bytes_per_datum sysfs attribute docs as it no longer exists.
 * A whole load of missing / fixing of kernel-doc for the core of IIO.
 * Document the trigger name sysfs attribute in the ABI docs.
 * Minor typos in the ABI docs related to power down modes.
