MediaTek extend the arm v7s descriptor to support up to 34 bits PA where the bit32 and bit33 are encoded in the bit9 and bit4 of the PTE respectively. Meanwhile the iova still is 32bits. Regarding whether the pagetable address could be over 4GB, the mt8183 support it while the previous mt8173 don't, thus keep it as is.

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.
