I searched, and this is the only place that uses the hisi prefix. Currently,
YAML check will report warnings due to mismatch any of the regexes defined
in Documentation/devicetree/bindings/vendor-prefixes.yaml

Is it not good to add hisi prefix to clear warnings?
"^hisi,.*":
  description: Hisilicon Limited, deprecated.

By the way, Hi Rob:
The license information in some YAML files is incorrect. Can you correct it in v5.11?
For example:
WARNING: DT binding documents should be licensed (GPL-2.0-only OR BSD-2-Clause)
#26: FILE: Documentation/devicetree/bindings/thermal/allwinner,sun8i-a83t-ths.yaml:1:
