Patrick Wildt df07233132 arm64: dts: rockchip: adjust SMMU interrupt type on rk3588
[ Upstream commit 8546cfd08a ]

The SMMU architecture requires wired interrupts to be edge triggered,
which does not align with the DT description for the RK3588.  This leads
to interrupt storms, as the SMMU continues to hold the pin high and only
pulls it down for a short amount when issuing an IRQ.  Update the DT
description to be in line with the spec and perceived reality.

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 reStructuredText 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.
