Subject: [PATCH v2 1/2] bindings: iio: adc: Add max11205 documentation file
Add bindings documentation file and MAINTAINERS entry for MAX11205.
Signed-off-by: Ramona Bolboaca <ramona.bolboaca@...log.com>
---
changes in v2:
- reference /schemas/spi/spi-peripheral-props.yaml in allOf
- use unevaluatedProperties:false and remove additionalProperties:false
- use generic node name and fix indentation in device-tree example
- wrap lines nearer to 75-80 chars in documentation
- add extra information to the description of the regulator
