Modern device tree bindings are supposed to be created as YAML-files in accordance with DT schema. This commit replaces Synopsys DW GPIO legacy bare text binding with YAML file. As before the binding file states that the corresponding dts node is supposed to be compatible with generic DW I2C controller indicated by the "snps,dw-apb-gpio" compatible string and to provide a mandatory registers memory range. It may also have an optional clock and reset phandle references. There must be specified at least one subnode with "snps,dw-apb-gpio-port" compatible string indicating the GPIO port, which would actually export the GPIO controller functionality. Such nodes should have traditional GPIO controller properties together with optional interrupt-controller attributes if the corresponding controller was synthesized to detect and report the input values change to the parental IRQ controller.

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.
