The Meson8/Meson8b/Meson8m2 SoCs have a register bank called SECBUS2 which contains registers for various IP blocks such as pin-controller bits for the BSD_EN and TEST_N GPIOs as well as some AO ARC core control bits. The registers can be accessed directly when not running in "secure mode". When "secure mode" is enabled then these registers have to be accessed through secure monitor calls. So far these SoCs are always known to boot in "non-secure mode". Add a binding documentation using syscon (as these registers are shared across different IPs) for the SECBUS2 registers.

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.
