19 Description
20 -----------
21 The ISL29003 is an integrated light sensor wit
22 ADC, I2C user programmable lux range select fo
23 I2C multi-function control and monitoring capa
24 provides 16-bit resolution while rejecting 50H
25 artificial light sources.
26
27 The driver allows to set the lux range, the bi
28 mode (see below) and the power state of device
29 value, of course.

32 Detection
33 ---------
34
35 The ISL29003 does not have an ID register whic
36 it, so the detection routine will just try to
37 address and consider the device to be present
38 transfer.
