sorry for noticing this only very late: I missed the #address-cells,
#size-cells and ranges property in my last review
do you have any change queued which requires this?
my understanding is that the drivers for all RTI children should use
the register offsets relative to the RTI start address. In that case
the child nodes neither have a unit-address nor a reg property, making
the last three properties unnecessary.


Regards
Martin
