Subject: pci and pcie device-tree binding - range No cells
Date: Mon, 10 Dec 2012 13:20:23 +0100 [thread overview]
Message-ID: <50C5D387.90908@monstr.eu> (raw)
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
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?
Thanks,
Michal
