Hi Grant and others,

I have a question regarding number of cells in ranges property
for pci and pcie nodes.

Linux pci/pcie powerpc DTSes contain 7 cells (xpedite5370.dts, sequoia.dts, etc)
but also 6 cells format too (mpc832x_mds.dts)

Here is shown 6 cells ranges format and describe

And also in documentation in the linux

Both format uses:
#size-cells = <2>;
#address-cells = <3>;

What is valid format?
