According to the AST2500/AST2520 specs, these SoCs support up to 228 GPIO
pins. However, 'gpio-ranges' value in 'aspeed-g5.dtsi' file is currently
setting the upper limit to 220 which isn't allowing access to all their
GPIOs. The correct upper limit value is 232 (actual number is 228 plus a
4-GPIO hole in GPIOAB). Without this patch, GPIOs AC5 and AC6 do not work
correctly on a AST2500 BMC running Linux Kernel v4.19

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.
