Thread your patches. Using git format-patch and send-email is the
easiest, but of course you can do it with other tools as long as you
thread it and do not send in HTML - like the ones here...

You do not have reg here, so no unit address. Do you see this is
different than all other regulator nodes?

No underscores, names do not match schema. This should be led-0 etc.

No underscores, generic node name, so this is probably tpm, isn't it?

Generic node name is needed. Isn't this pmic?

Why adding status here? Was it disabled?

Do not add dead code. All three comments above do not really fit
mainline DTS.

Generic node names. Schema requires it, so it means you did not test
your DTS with `make dtbs_check`. Your DTS should pass almost all DT
schema tests.
