Will Deacon e149573b2f of: property: Add device link support for "iommu-map"
Commit 8e12257dea ("of: property: Add device link support for iommus,
mboxes and io-channels") added device link support for IOMMU linkages
described using the "iommus" property. For PCI devices, this property
is not present and instead the "iommu-map" property is used on the host
bridge node to map the endpoint RequesterIDs to their corresponding
IOMMU instance.

Add support for "iommu-map" to the device link supplier bindings so that
probing of PCI devices can be deferred until after the IOMMU is
available.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
