[PATCH 00/11] staging: iio: tsl2x7x: staging cleanups

[Brian Masney <masneyb@onstation.org>]

Here is another set of staging cleanups for the tsl2x7x driver. The
driver is about ready to move out of staging. I want to test a few other
things first before submitting a patch to move the driver out of
staging.

High-level changes in this series:
- Interrupts and IIO events now work properly
. Split out interrupt and persistence variables into separate ALS and
  proximity variables to improve code readability.
- Simplify code, remove unnecessary code, and improve code readability.

# How to test the interrupts

cd /sys/bus/iio/devices/iio:device0

echo 0 > events/in_intensity0_thresh_falling_value
echo 512 > events/in_intensity0_thresh_rising_value
echo 1 > events/in_intensity0_thresh_rising_en

# proximity0 already has threshold range at [0,512]
echo 1 > events/in_proximity0_thresh_rising_en

Run iio_event_monitor tsl2772 and verify that events are sent properly.

Question: Should I use in_intensity0_thresh_either_en instead of
in_intensity0_thresh_{rising,falling}_en? The same goes for the
proximity0. This is the current contents of the events/ directory:

in_intensity0_thresh_either_period
in_intensity0_thresh_falling_en
in_intensity0_thresh_falling_value
in_intensity0_thresh_rising_en
in_intensity0_thresh_rising_value
in_proximity0_thresh_either_period
in_proximity0_thresh_falling_en
in_proximity0_thresh_falling_value
in_proximity0_thresh_rising_en
in_proximity0_thresh_rising_value
