Scope of the change is limited to GPIO pins used by board specific
device drivers which will be updated by follow-up patches of the
series. Those are some OMAP GPIO (gpio-0-15) and most of Amstrad Delta
latch2 GPIO bank pins. Remaining pins of those banks, as well as
Amstrad Delta latch1 pins, will be addressed later.
Assign a label ("latch2") to the bank, enumerate its pins and put that
information, together with OMAP GPIO bank pins, in GPIO lookup tables.
Assign lookup tables to devices as soon as those devices are registered
and their names can be obtained.
A step froward in:
- removal of hard-coded GPIO numbers from drivers,
- removal of board mach includes from drivers,
- switching to dynamically assigned GPIO numbers.

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.
