You're right, it is better as it is defined in dtschema/schemas/property-units.yaml from https://github.com/devicetree-org/dt-schema.git I used kOhms as it already used in the device tree (by bindings/regulator/qcom-labibb-regulator.yaml), but in retrospect, this example should not be followed. A v3 is coming soon.
