Release the parent interrupt request during runtime suspend, allowing the parent interrupt controller to enter runtime suspend if there are no active users. This change may not have a visible impact if the parent controller is the GIC, but it can enable significant power savings for parent IRQ controllers like IRQSteer inside a subsystem on i.MX8 SoCs. Releasing the parent IRQ provides an opportunity for the subsystem to enter suspend states if there are no active users.

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.
