For correct terminology, I'd prefer to replace this line with:

- msi-parent: a list of phandle + msi-specifier pairs for MSI controllers

An msi-specifier may be zero cells, per
Documentation/devicetree/bindings/interrupt-controller/msi.txt, much
like other *-specifiers.

The rest of this is fine, modulo the '.' which should be a '/'. in the
path.

With those changes:
