Jose Ignacio Tornos Martinez ba2274dcfd net: wwan: t7xx: Add AP CLDMA 
At this moment with the current status, t7xx is not functional due to
problems like this after connection, if there is no activity:
[   57.370534] mtk_t7xx 0000:72:00.0: [PM] SAP suspend error: -110
[   57.370581] mtk_t7xx 0000:72:00.0: can't suspend
    (t7xx_pci_pm_runtime_suspend [mtk_t7xx] returned -110)
because after this, the traffic no longer works.

The complete series 'net: wwan: t7xx: fw flashing & coredump support'
was reverted because of issues with the pci implementation.
In order to have at least the modem working, it would be enough if just
the first commit of the series is re-applied:
d20ef656f9 net: wwan: t7xx: Add AP CLDMA
With that, the Application Processor would be controlled, correctly
suspended and the commented problems would be fixed (I am testing here
like this with no related issue).

This commit is independent of the others and not related to the
commented pci implementation for the new features: fw flashing and
coredump collection.

Use v2 patch version of d20ef656f9 as JinJian Song suggests
(https://patchwork.kernel.org/project/netdevbpf/patch/20230105154215.198828-1-m.chetan.kumar@linux.intel.com/).

Original text from the commit that would be re-applied:

    d20ef656f9 net: wwan: t7xx: Add AP CLDMA
    Author: Haijun Liu <haijun.liu@mediatek.com>
    Date:   Tue Aug 16 09:53:28 2022 +0530

    The t7xx device contains two Cross Layer DMA (CLDMA) interfaces to
    communicate with AP and Modem processors respectively. So far only
    MD-CLDMA was being used, this patch enables AP-CLDMA.

    Rename small Application Processor (sAP) to AP.

README 

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.
