Now when all MPP pins are properly defined and every MPP pin has GPIO
function, always checks for errors in armada_37xx_gpio_request_enable()
function when calling armada_37xx_pmx_set_by_name(). Function
armada_37xx_pmx_set_by_name() should not return "not supported" error
anymore for any GPIO pin when requesting GPIO mode.
Fixes: 87466ccd9401 ("pinctrl: armada-37xx: Add pin controller support for Armada 37xx")

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.
