Fetch a reference to the optional shared reset control and deassert it if it exists. Optional because not all platforms that use this driver have a reset attached to the reset block. Shared because some platforms that use the reset (at least Mobileye EyeQ5) share the reset across banks. Do not keep a reference to the reset control as it is not needed afterwards; the driver does not handle suspend, does not use runtime PM, does not register a remove callback and does not support unbinding from sysfs (made explicit with suppress_bind_attrs). The operation is done in nmk_gpio_populate_chip(). This function is called by either gpio-nomadik or pinctrl-nomadik, whoever comes first. This is here for historic reasons and could probably be removed now; it seems gpio-ranges enforces the ordering to be pinctrl-first. It is not the topic of the present patch however.

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.
