Linux kernel source tree

In order to provide proper debug interface it's required to have domain names available when the domain is added. Non fwnode based architectures like x86 have no way to do so. It's not possible to use domain ops or host data for this as domain ops might be the same for several instances, but the names have to be unique. Extend the irqchip fwnode to allow transporting the domain name. If no node is supplied, create a 'unknown-N' placeholder. Warn if an invalid node is supplied and treat it like no node. This happens e.g. with i2 devices on x86 which hand in an ACPI type node which has no interface for retrieving the name.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
