Gpio complexity is just masking the fact that offset is always 0..n and writes to bits 0..n of some memory address. Because of this whole thing can just me converted to use GPIO_GENERIC and avoid duplications of a lot of driver custom functions. So use bgpio_init instead of custom code adding GPIO_GENERIC dependency to the Kconfig file. Also to make easier using bgpio_init function offset for each gpio bank, enumeration where register were defined has been replaced in favour of some macros which handle each gpio offset taking into account the bank where are located. Because of this change write and read functions which are being used for remaining irq handling stuff have been updated also as well as its dependencies 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.
