Do we want to use

This actually also applies to <dt-bindings/...> files.

One interrupt is missing. According to the documentation, "tei" and

Please add interrupt-names.

This looks like a weird name ;-)
In addition, it should be the consumer clock name, not the provider
clock name.

As I think this is shared by RZ/G2L and RZ/G2LC, it belongs to
r9a07g044.dtsi.

I think (at least) the first CPU core should be in the base
r9a07g044.dtsi file.
Probably the second CPU core should be in the base file, too, and
removed by /delete-node/ in r9a07g044l1.dtsi?
