UART3 on the PG pingroup on the R40 SoC is commonly used to connect the bluetooth controller in a WiFi+Bluetooth combo chip, with the WiFi bits also on the PG pingroup. This patch adds two device nodes for UART3 on PG pingroup, one for the RX/TX pins, and one for the RTS/CTS pins. Consumers can reference either just the RX/TX pinmux setting or both, depending on the application.

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.
