No, don't delete properties. First of all, why you do not have this
supply here? I doubt it... Especially that this DTS has vbat-supply
regulator!

Second, define the properties where applicable instead.

This is not what your binding is saying. You just introduced new
dtbs_check warnings :(

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).


Best regards,
Krzysztof
