Franklin, I agree this is the way to go but I think it is a bit risky
to change it in dylan.

I think it could be included in meta-ti or other layers (in case it is
need for dylan) but it has breakage risk as noticed today in some
behaviour change as found in meta-xilinx.

Paul, please be conservative about this and my previous linux-dtb
patch. In case it is going to be applied in dylan we need to let it
sleep some more time in master to find any other side effect due the
behaviour change.

Regards,
