Most gpio chips have two cells for interrupts and this should be also. Set this property in the device tree accordly fixing this up. In order to make this working properly the xlate function for the irq_domain must be updated to use the 'irq_domain_xlate_twocell' one in the driver. One more minimal change is needed two refer gpio's interrupt-parent from other nodes which is to add new 'gpio' label in the device tree.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
