One comment inline. I'll also be needing an ack from Analog on this,
preferably Michael's.

You should also update the MAINTAINERS file.
Maybe in a following patch.
It looks like there is not entry in there, so maybe you need to add a new
one.
Something like:
ANALOG DEVICES INC AD7780 DRIVER
M: Michael Hennerich
M: Renato Lui Geh
L: linux-...@vger.kernel.org
W: http://ez.analog.com/community/linux-device-drivers
S: Supported
F: drivers/iio/adc/ad7780.c
F: Documentation/devicetree/bindings/iio/adc/adi,ad7780.yaml
This should be after this block
ANALOG DEVICES INC AD7768-1 DRIVER
Note that I added you as a co-maintainer.
If you want, you do not need to add that line.

+description: |
+ The ad7780 is a sigma-delta analog to digital converter. This driver provides
+ reading voltage values and status bits from both the ad778x and ad717x
series.
+ Its interface also allows writing on the FILTER and GAIN GPIO pins on the
+ ad778x.
+
+ Specifications on the converters can be found at:
