The aspeed VUART runs at LPC bus frequency, rather than being restricted to a typical UART baud rate. This means that the VUART can receive a lot of data, which can overrun tty flip buffers, and/or cause a large amount of interrupt traffic. This change implements the uart_port->throttle & unthrottle callbacks, implemented by disabling the receiver line status & received data available IRQs.

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.
