The interrupt router has 32 inputs, and up to 15 outputs connected to the MIPS CPU's interrupts. The way these are mapped to each other is runtime configurable. This controller can also mask individual interrupt sources, and has a status register to indicate pending interrupts. This means the controller is not transparent, and the use of "interrupt-map" inappropriate. Instead, a list of parent interrupts should be specified. Two-part compatibles are introduced to be able to require "interrupts" for new devicetrees. For backward compatibility "interrupt-map" is still allowed on these new compatibles, but deprecated. The old compatible, with required "interrupt-map" and "#address-cells", is also deprecated. The relevant descriptions are added or extended to more clearly describe the functionality of this controller. To prevent spurious changes to the binding when more SoCs are added, "allOf" is used with one "if", and the compatible enum only has one item. The example is updated to provide a correct example for RTL8380 SoCs.

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.
