From 6efd853303a5eea90a21a1ec496005317b6cc2e3 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Wed, 28 Aug 2024 21:16:20 +0530 Subject: [PATCH] dt-bindings: PCI: qcom,pcie-sm8450: Add 'global' interrupt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. Though adding a new interrupt will break the ABI, it is required to accurately describe the hardware.
