Marc Zyngier 5f774f5e12 irqchip/git-v3-its: Implement irq_retrigger callback for device-triggered LPIs
It is pretty easy to provide a retrigger callback for the ITS,
as it we already have the required support in terms of
irq_set_irqchip_state().

Note that this only works for device-generated LPIs, and not
the GICv4 doorbells, which should never have to be retriggered
anyway.

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.
