[v1] PCI: qcom: Simulate PCIe hotplug using 'global' interrupt

[PATCH 05/14] dt-bindings: PCI: qcom-ep: Document "linux,pci-domain" property

Posted by Manivannan Sadhasivam via B4 Relay 1 year, 6 months ago

From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>

'linux,pci-domain' property provides the PCI domain number for the PCI
endpoint controllers in a SoC. If this property is not present, then an
unstable (across boots) unique number will be assigned.

Use this property to specify the domain number based on the actual hardware
instance of the PCI endpoint controllers in a SoC.

You aren't "documenting" it here as the subject says, just using it in 
the example.

I think this should be squashed into the previous patch
