Instead of create a custom irq_domain for this chip, use 'gpiochip_set_chained_irqchip' from GPIOLIB_IRQCHIP. It is ok to call this function several times. We have to manually mark the line with 'IRQF_SHARED' and then loop over the three banks until you find a hit. There were some problems with removing an irqchip like that but this driver is a bool so it might work just fine. After this changes the functions 'mediatek_gpio_to_irq' is not needed anymore and also the 'gpio_irq_domain' field from the state container. Instead of use the custom irq domain in the irq handler use the associated domain from the gpio_chip in 'irq_find_mapping' function. Function 'mediatek_gpio_bank_probe' has been moved a it to the botton to have all the irq related functions together and avoid some forward declarations to resolve some symbols along the code.

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.
