What board specific property? This description looks wrong.

What error are you trying to fix exactly? The example used below is actually how
it exactly appears in the J721E dts files, and there are no errors with
dt_binding_check.

This is more a cleanup than a fix.  You can look through the original binding
submission patches to see why it is done like this.

If this is triggered by the changes you are making to k3.yaml file as part of
the J721E EAIK changes, then you probably may want to look at how you are doing
that again. Looks like the k3.yaml file is being modified now to enforce
"board-compatible", "soc-compatible" which may have triggered an error in this file.

Please evaluate if you need to modify it to support just the "soc-compatible" as
one of the items.

While this may be resolving the dt_bindings_check you might be seeing with the
modified k3.yaml, note that "soc" property is not used on K3 dts files, you
might be creating confusion for people who look at this example and the actual
usage.
