14	Description
15	-----------
16	The ISL29003 is an integrated light sensor with a 16-bit integrating type
17	ADC, I2C user programmable lux range select for optimized counts/lux, and
18	I2C multi-function control and monitoring capabilities. The internal ADC
19	provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by
20	artificial light sources.
21	
22	The driver allows to set the lux range, the bit resolution, the operational
23	mode (see below) and the power state of device and can read the current lux
24	value, of course.

27	Detection
28	---------
29	
30	The ISL29003 does not have an ID register which could be used to identify
31	it, so the detection routine will just try to read from the configured I2C
32	addess and consider the device to be present as soon as it ACKs the
33	transfer.

36	Sysfs entries
37	-------------
38	
39	range:
40		0: 0 lux to 1000 lux (default)
41		1: 0 lux to 4000 lux
42		2: 0 lux to 16,000 lux
43		3: 0 lux to 64,000 lux

49		3: 2^4 cycles
50	
51	mode:
52		0: diode1's current (unsigned 16bit) (default)
53		1: diode1's current (unsigned 16bit)
54		2: difference between diodes (l1 - l2, signed 15bit)
55	
56	power_state:
57		0: device is disabled (default)
58		1: device is enabled
59	
60	lux (read only):
61		returns the value from the last sensor reading
