It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Although I wonder why there is no error report from the bot.

Drop "Device Tree Bindings"

This goes after description. Several existing files have it in other
place, but if doing changes then well...

Drop or say something else than title.

Drop description, obvious.

default? Or missing property has other meaning...

Where is it defined? You added it as it was a common property, so where
is the one definition? Maybe you wanted to use other property from
rtc.yaml which is deprecated, so obviously not...
