[PATCH] dt-bindings: iio: adc: ad7923: Add dt-bindings for AD7928

[Daniel Junho]

From: Daniel Junho <djunho@xxxxxxxxx>

Add device tree bindings documentation for AD7923 adc in YAML format.

Tested with:
make ARCH=arm dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/iio/adc/adi,ad7923.yaml
make ARCH=arm dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/iio/adc/adi,ad7923.yaml

Hi,

I got maintainers from the driver authors list. Let me know if this is
fine.

Thanks.
