It's a double disable, isn't it?

Ordering is broken. All overrides/extends are ordered by label name.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Since these are disabled, aliases do not belong to DTSI, but to board.

Also, explain why do you need them.

Not ordered. Keep nodes sorted by unit address, at least within the
group of devices you add.

reg is second property. reg-names and ranges follow.
