Currently msi-parent is used by a few bindings to describe the relationship between a PCI root complex and a single MSI controller, but this property does not have a generic binding document. Additionally, msi-parent is insufficient to describe more complex relationships between MSI controllers and devices under a root complex, where devices may be able to target multiple MSI controllers, or where MSI controllers use (non-probeable) sideband information to distinguish devices. This patch adds a generic binding for mapping PCI devices to MSI controllers. This document covers msi-parent, and a new msi-map property (specific to PCI*) which may be used to map devices (identified by their Requester ID) to sideband data for each MSI controller that they may target.
