Enable i2c-mux-gpio devices to be defined via ACPI. The idle-state property translates directly to a fwnode_property_*() call. The child reg property translates naturally into _ADR in ACPI. The i2c-parent binding is a relic from the days when the bindings dictated that all direct children of an I2C controller had to be I2C devices. These days that's no longer required. The i2c-mux can sit as a direct child of its parent controller, which is where it makes the most sense from a hardware description perspective. For the ACPI implementation we'll assume that's always how the i2c-mux-gpio is instantiated.

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.
