Changes in v6:
Patch 1:
	- nothing changed.
Patch 2, 3:
	- added reviewed-by's which were lost when new versions were added.
Patch 4:
	- fixed kbuild warning by adding a buffer overflow check in
	  adxl372_buffer_postenable().
Patch 5, 6:
	- nothing changed

Changes in v5:
Patch 1, 2:
	- nothing changed
Patch 3:
	- added a new readable_noinc operation based on feedback from
	  Mark Brown
Patch 4:
	- added a readable_noinc callback based on the changes from the
	  previous patch.
Patch 5, 6:
	- nothing changed

Changes in v4:
Patch 1:
	- used a lookup table in adxl372_set_activity_threshold() instead
	  of a switch(case).
Patch 2: 
	- removed the interrupt-parent from the bindings.
Patch 3:
	- renamed regmap_pipe_read() stub to regmap_noinc_read().
Patch 4:
	- removed the adxl372_read_fifo() wrapper and directly called
	  regmap_noinc_read().
	- called iio_triggered_buffer_predisable() before doing the local
	  changes.
Patch 5:
	- nothing changed.
Patch 6:
	- nothing changed.

Changes in v3:
Patch 1, 2:
	- nothing changed
Patch 3:
	- changed the name from regmap_pipe_read() to regmap_noinc_read()
	- added a check for readable registers
Patch 4:
	- dropped the fifo peak mode
	- corrected the patch based on feedback from Peter Meerwald-Stadler.
Patch 5 and 6:
	- nothing changed

Changes in v2:
Patch 1:
	- removed ADXL372_RD_FLAG_MSK and ADXL372_WR_FLAG_MSK macros.
	- handled regmap read/write by setting reg_bits and pad_bits
	  fields in regmap_config struct.
	- removed the buffer specifications when defining the channels.
	- changed the activity and inactivity thresholds.
	- added two new functions for setting the activity and inactivity
	  timers: adxl372_set_inactivity_time_ms() and
	  adxl372_set_activity_time_ms().
Patch 2:
	- introduced all the DT bindings in a single patch.
Patch 3:
	- backported the patch based on this discussion: 
          https://lkml.org/lkml/2016/6/16/548.
	- this patch is required as the regmap_pipe_read() API will be used 
	  to read the data from the FIFO.
Patch 4:
	- removed DT bindings changes from this patch.
	- removed the linux/gpio/consumer.h header.
	- used regmap_pipe_read() instead of regmap_bulk_read() when
	  reading data from the FIFO.
	- used multiple regmap_write() calls instead of a single
	  regmap_bulk_write() if there is no fast path.
	- used be32_to_cpu() inside the adxl372_get_status() function.
	- added a new in_accel_x&y&z_peak scan element which allows the
	  user to set the FIFO into XYZ peak mode.
	- used a adxl372_axis_lookup_table() to determine the fifo format
	  from the active_scan_mask.
	- made IRQ optional.
Patch 5 and 6:
	- nothing changed
