Even just calculating the register addresses is a lot of work.
You can't just take the property values for the device as-is, you have
to walk up to the root applying 'range' property translations to the
register addresses.
And there are special cases and quirks all over the place.
The code to do this in the Linux kernel is several thousand lines of
code.
