Drop the comma and leading zero.
Even though this is how it appears in the actual DT?
Yes, those will need to get fixed, too.
Sorry, I just want to confirm that I understand why this needs to be
fixed. The parent node has #address-cells = <2>, and the practice of
specifying two cells in the node name is consistent with what I see in
http://www.devicetree.org/Device_Tree_Usage.
However in the device tree usage example one can interpret the two cells
as being two different components of the address, whereas in our case we
are using two cells because the address is 64-bit - hence we should
specify it in the name as a single entity. Is this correct?
Thanks,
Alex.
