[PATCH v6 3/8] dt-bindings: PCI: qcom,pcie-x1e80100: Add 'global' interrupt

2024-10-11T10:42:13Z

Document 'global' SPI interrupt along with the existing MSI interrupts so
that QCOM PCIe RC driver can make use of it to get events such as PCIe
link specific events, safety events, etc.

Though adding a new interrupt will break the ABI, it is required to
accurately describe the hardware.
