Subject: [PATCH v2 0/3] iio: light: opt3001: add support for TI's opt3002
 light sensor

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.

Changes in v2:
- Move dt-binding patch to before implementation.
- Fix dt-binding compatible definition.
- Clarify bug description for missing full-scale range value.
- Remove model enum from chip info and all in-function switch-case
  statements.
- Move model-specific channels and mathematic constants to chip info.
- Add valid match data to opt3001_id array
- Skip call to function opt3001_read_id() if model doesn't have a device
  id register.
- Link to v1: https://lore.kernel.org/r/20240905-add_opt3002-v1-0-a5ae21b924fb@axis.com
