-Description
------------
-The ISL29003 is an integrated light sensor with a 16-bit integrating type
-ADC, I2C user programmable lux range select for optimized counts/lux, and
-I2C multi-function control and monitoring capabilities. The internal ADC
-provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by
-artificial light sources.
-
-The driver allows to set the lux range, the bit resolution, the operational
-mode (see below) and the power state of device and can read the current lux
-value, of course.
-
-
-Detection
----------
-
-The ISL29003 does not have an ID register which could be used to identify
-it, so the detection routine will just try to read from the configured I2C
-addess and consider the device to be present as soon as it ACKs the
-transfer.

--------------
-
-range:
- 0: 0 lux to 1000 lux (default)
- 1: 0 lux to 4000 lux
