recommended

It might make sense to mention that the default is expected to be high precision
if not specified.

I thought its OK to set the maintainer from the list shown with
get_maintainer.pl here. I don't mind take care of this file - there will be 
small changes only in case the dt-schema change and requires updates.

I put me here, if that is acceptable.

No, it isn't. Jean and I are the maintainers for the hwmon
subsystem, but that doesn't mean or suggest that we should
be listed as maintainers in individual files.

Either you, or none.

[PATCH v3 2/2] devicetree: hwmon: shtc1: Add sensirion,shtc1.yaml

[Chris Ruehl]

Add documentation for the newly added DTS support in the shtc1 driver.
To align with the drivers logic to have high precision by default
a boolean sensirion,low_precision is used to switch to low precision.
