Some drivers (e.g. gpio-mt7621 and gpio-brcmstb) have multiple gpiochip banks within a single device. Unfortunately, the gpio-ranges property of the device node was being applied to every gpiochip of the device with device relative GPIO offset values rather than gpiochip relative GPIO offset values. This commit makes use of the gpio_chip offset value which can be non-zero for such devices to split the device node gpio-ranges property into GPIO offset ranges that can be applied to each of the relevant gpiochips of the device.

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.
