From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lucas Stach Subject: [PATCH] PCI: add missing DT binding for linux,pci-domain property Date: Tue, 4 Nov 2014 12:47:40 +0100 Message-ID: <1415101660-26450-1-git-send-email-l.stach@pengutronix.de> Return-path: Sender: linux-pci-owner@vger.kernel.org To: Rob Herring , Pawel Moll , Mark Rutland , Ian Campbell , Kumar Gala Cc: devicetree@vger.kernel.org, Bjorn Helgaas , linux-pci@vger.kernel.org, Liviu Dudau List-Id: devicetree@vger.kernel.org This property was added by 41e5c0f81d3e (of/pci: Add pci_get_new_domain_nr() and of_get_pci_domain_nr()) without the required binding documentation. As this property will be supported by a number of host bridge drivers going forward, add it to the common PCI binding doc. Signed-off-by: Lucas Stach --- This is a non-critical fix, but may still qualify for 3.18-rc as the property was added in this release cycle. --- Documentation/devicetree/bindings/pci/pci.txt | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/Documentation/devicetree/bindings/pci/pci.txt b/Documentation/devicetree/bindings/pci/pci.txt index 41aeed38926d..b754f786ed5e 100644 --- a/Documentation/devicetree/bindings/pci/pci.txt +++ b/Documentation/devicetree/bindings/pci/pci.txt @@ -7,3 +7,13 @@ And for the interrupt mapping part: Open Firmware Recommended Practice: Interrupt Mapping http://www.openfirmware.org/1275/practice/imap/imap0_9d.pdf + +Additionally to the properties specified in the above standards a host bridge +driver implementation may support the following properties: + +- linux,pci-domain: + If present this property assigns a fixed PCI domain number to a host bridge, + otherwise an unstable (across boots) unique number will be assigned. + It is recommended to either not set this property at all or set it for all + host bridges in the system, otherwise potentially conflicting domain numbers + may be assigned to root buses behind different host bridges. -- 2.1.1
