When a bus specifies #address-cells > 2, of_bus_default_map()
now assumes that the mapping isn't for a physical address but
rather an identifier that needs to match exactly.

This is required by bindings that use multiple cells to
translate a resource to the parent bus (device index, type,
...).

Hi Rob,

Were you going to take this through your DT tree? I'm trying to
reduce the number of patches in this series to make it more
manageable and split it into smaller chunks. There are also a
couple of issues that need to be resolved so I don't know if I can
get the whole series into shape for 3.7.

However if you don't think this patch is useful to be applied by
itself I can also carry it until the complete series is ready.

Rob,

Are you able to take this patch now for 3.7, or should it be held off
until the Tegra PCIe driver is re-written and requires this
functionality (in which case I'd expect to take this through the Tegra
tree at that time).

For reference, it's at http://patchwork.ozlabs.org/patch/173497/.

Thanks.
