The default gpiolib-of implementation does not work with the multiple gpiochip banks per device structure used for example by the gpio-mt7621 and gpio-brcmstb drivers. To fix these kind of situations driver code is forced to fill the names to avoid the gpiolib code to set names repeated along the banks. Instead of continue with that antipattern fix the gpiolib core function to get expected behaviour for every single situation adding a field 'offset' in the gpiochip structure. Doing in this way, we can assume this offset will be zero for normal driver code where only one gpiochip bank per device is used but can be set explicitly in those drivers that really need more than one gpiochip.

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.
