Subject: [PATCH 00/12] ACPI/OF: Upgrade MSI/IOMMU ID mapping APIs
Date: Thu, 21 May 2020 13:59:56 +0100
Message-ID: <20200521130008.8266-1-lorenzo.pieralisi@arm.com> (raw)

Firmware bindings provided in the ACPI IORT table[1] and device tree
bindings define rules to carry out input/output ID mappings - ie
retrieving an IOMMU/MSI controller input ID for a device with a given
ID.

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.
