TI's opt3002 light-to-digital sensor provides the functionality of an optical power meter within a single device. It shares a lot of similarities with their opt3001 model but has a wide spectral bandwidth, ranging from 300 nm to 1000 nm. This patch set adds support for the TI opt3002 by extending the opt3001 driver. In addition, a missing full-scale range value for the opt3001 is added, resulting in higher precision when setting event trigger values.
