[PATCH v6 0/3] iio: add support for hardware fifo

[Octavian Purdila <octavian.purdila@intel.com>]

Changes since v5:

 * remove hwfifo_get_watermark operation from iio_info operations; the
   driver can expose it dirrectly as a read-only buffer attribute and
   there is not much gain from do it in the core

 * in the case of non-blocking read flush with the full to read amount

 * fix a few spelling errors

 * add hwfifo_watermark_min, hwfifo_watermark_max,
   hwfifo_watermark_available, hwfifo_enabled attributes to give
   userspace more information of how to select a watermark that can
   used to enable the hardware fifo

 * rename hwfifo_flush to hwfifo_flush_to_buffer

 * bmc150: avoid changing the iio_info to keep it constant

 * bmc150: rename irq and threaded irq handlers
