By allowing platform MSI domain to be created on ACPI platforms, a platform device MSI domain can be set-up when it is probed. In order to do that, the MSI domain the platform device connects to should be retrieved, so the iort_get_platform_device_domain() is introduced to retrieve the domain from the IORT kernel layer. With the domain retrieved, we need a proper way to set the domain to platform device. Given that some platform devices (irqchips) require the MSI irqdomain to be their interrupt parent domain, the MSI irqdomain should be determined before platform device is probed but after the platform device is allocated which means that the code setting up the MSI irqdomain, ie acpi_configure_pmsi_domain() should be called in acpi_platform_notify() (that is triggered after adding a device but before the respective driver is probed) for the platform MSI domain code set-up path to work properly.

README
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.
