OK peter you win :-)
I am going to try a simple experiment on my tree, which is to have a 'dts' in each directory, with a spec of the chip and optional defaults -- I do not like the defaults in the dts, I really feel they belong in kconfig but -- and I will try to GENERATE the .h file from the pre-chip dts.
That will be my homework for next week, will report back.
I will pause LX port until I test this.
