Loongson-2K0300 ships a GPIO controller whose input/output control logic is similar to previous generation of SoCs. Additionally, it acts as an interrupt-controller supporting both level and edge interrupts and has a distinct reset signal. Describe its compatible in devicetree. We enlarge the maximum value of ngpios to 128, since the controller technically supports at most 128 pins, although only 106 are routed out of the package. Properties for interrupt-controllers and resets are introduced and limited as LS2K0300 only.

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 reStructuredText 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.
