commit 892cb524ae8a27bf5e42f711318371acd9a9f74a upstream.
Since IRQF_NO_SUSPEND used for imx mailbox driver, that means this irq
can't be used for wakeup source so that can't wakeup from freeze mode.
Add pm_system_wakeup() to wakeup from freeze mode.
Fixes: b7b2796b9b31e("mailbox: imx: ONLY IPC MU needs IRQF_NO_SUSPEND flag")

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.
