44 MSI support (optional):
46 For older platforms without MSI integrated in the GIC, iProc PCIe core provides
47 an event queue based MSI support. The iProc MSI uses host memories to store
48 MSI posted writes in the event queues
50 On newer iProc platforms, gicv2m or gicv3-its based MSI support should be used
52 - msi-map: Maps a Requester ID to an MSI controller and associated MSI
55 - msi-parent: Link to the device node of the MSI controller, used when no MSI
56 sideband data is passed between the iProc PCIe controller and the MSI
60 the use of 'msi-map' and 'msi-parent':

64 When the iProc event queue based MSI is used, one needs to define the
65 following properties in the MSI device node:
66 - compatible: Must be "brcm,iproc-msi"
67 - msi-controller: claims itself as an MSI controller
71 - brcm,pcie-msi-inten: Needs to be present for some older iProc platforms that
72 require the interrupt enable registers to be set explicitly to enable MSI
99 msi-parent = <&msi0>;
