[POWERPC] #address-cells & #size-cells properties are not inherited

Browse Source

In general, the format of an address for a device is defined by the
parent bus type, based on the #address-cells and #size-cells
property. In the absence of such a property, the parent's parent
values are used, etc... The kernel requires the root node to have
those properties defining addresses format for devices directly mapped
on the processor bus.
properties. Note that the parent's parent definitions of #address-cells
and #size-cells are not inhereted so every node with children must specify
them. The kernel requires the root node to have those properties defining
addresses format for devices directly mapped on the processor bus.
Those 2 properties define 'cells' for representing an address and a
size. A "cell" is a 32-bit number. For example, if both contain 2
