[PATCH 12/14] dt-bindings: PCI: qcom,pcie-sm8450: Add 'global' interrupt
From: Manivannan Sadhasivam via B4 Relay
Date: Mon Jul 15 2024 - 13:36:17 EST
From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>
Qcom PCIe RC controllers are capable of generating 'global' SPI interrupt
to the host CPU. This interrupt can be used by the device driver to
identify events such as PCIe link specific events, safety events, etc...
Hence, document it in the binding along with the existing MSI interrupts.
