Adding documentation why j721s2 compatible is correct for j784s4 is
needed.

https://docs.kernel.org/devicetree/bindings/dts-coding-style.html

"Nodes on any bus, thus using unit addresses for children, shall be
ordered by unit address in ascending order. Alternatively for some
subarchitectures, nodes of the same type can be grouped together,
e.g. all I2C controllers one after another even if this breaks unit
address ordering."

Any specific reason to keep this patch ordering?

^^ j721s2-gpu: please clarify in commit message.
