30 -------------------
32 - msi-map: Maps a Requester ID to an MSI controller and associated
33   msi-specifier data. The property is an arbitrary number of tuples of
34   (rid-base,msi-controller,msi-base,length), where:
36   * rid-base is a single cell describing the first RID matched by the entry.
38   * msi-controller is a single phandle to an MSI controller
40   * msi-base is an msi-specifier describing the msi-specifier produced for the
44     following the rid-base.
46   Any RID r in the interval [rid-base, rid-base + length) is associated with
47   the listed msi-controller, with the msi-specifier (r - rid-base + msi-base).
49 - msi-map-mask: A mask to be applied to each Requester ID prior to being mapped
50   to an msi-specifier per the msi-map property.
52 - msi-parent: Describes the MSI parent of the root complex itself. Where
