At the moment these firmware bindings are used exclusively for PCI devices and their requester ID to IOMMU/MSI id mapping but there is nothing PCI specific in the ACPI and devicetree bindings that prevent the firmware and kernel from using the firmware bindings to traslate device IDs for any bus that requires its devices to carry out input/output id translations. The Freescale FSL bus is an example whereby the input/output ID translation kernel code put in place for PCI can be reused for devices attached to the bus that are not PCI devices. This series updates the kernel code to make the MSI/IOMMU input/output ID translation PCI agnostic and apply the resulting changes to the device ID space provided by the Freescale FSL bus.
