According to ePAPR spec.
"
The #address-cells and #size-cells properties may be used in any device
node that has children in the device tree hierarchy and describes how
child device nodes should be addressed. The #address-cells property
defines the number of <u32> cells used to encode the address field in
a child node’s reg property. The #size-cells property defines the number
of <u32> cells used to encode the size field in a child node’s reg
property.
The #address-cells and #size-cells properties are not inherited from
ancestors in the device tree. They shall be explicitly defined.
An ePAPR-compliant boot program shall supply #address-cells and #size-cells
on all nodes that have children.
If missing, a client program should assume a default value of 2 for
An ePAPR-compliant boot program shall supply #address-cells and #size-cells
on all nodes that have children.
"
So need to use the parent's address-cells and size-cells property.
