in line with my comment in the binding, please split the system-on-module
parts into a rk3588-firefly-core-3588j.dtsi and then include that file here.

please sort properties (compatible, regs, [alphabetically], status) and please
drop those comments at the end.
Applied to all regulator nodes

that mem-supply property is not specified and also is not necessary here.
Same for the other cases above.

default status is always "okay", so no need to add it for new nodes.
Same for possible other places in this file.

if anything, that include needs to live in include/dt-bindings/something
and needs to be a separate patch, if you really need that
