The ICU can handle several type of interrupt, each of them being handled differently on AP side. On CP side, the ICU should be able to make the distinction between each interrupt group by pointing to the right parent. This is done through the introduction of new bindings, presenting the ICU node as the parent of multiple ICU sub-nodes, each of them being an interrupt type with a different interrupt parent. ICU interrupt 'clients' now directly point to the right sub-node, avoiding the need for the extra ICU_GRP_* parameter. ICU subnodes are probed automatically with devm_platform_populate(). If the node as no child, the probe function for NSRs will still be called 'manually' in order to preserve backward compatibility with DT using the old binding.

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.
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.
