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 http://devicetree.org/Device_Tree_Usage#PCI_Host_Bridge And also in documentation in the linux Documentation/devicetree/bindings/pci/83xx-512x-pci.txt Both format uses: #size-cells = <2>; #address-cells = <3>; What is valid format?
