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 v3:
- Include difference between opt3001 and opt3002 in commit message for
  dt-binding patch.
- Remove whitespace between tags in commit message for opt3002 patch.
- Rename opt300x_chip_info to opt3001_chip_info.
- Add documentation for mathematical constants in opt3001_chip_info.
- Only check return value after opt3001_read_id if chip has id register
  in opt3001_probe.
- Change opt3002 channel mask to IIO_CHAN_INFO_RAW.
- Link to v2: https://lore.kernel.org/r/20240913-add_opt3002-v2-0-69e04f840360@axis.com

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.
