[ Upstream commit 7c41ea57be ]
If debugging on i.MX is enabled DEBUG_IMX_UART_PORT defines which UART
is used for the debug output. If however debugging is off don't only
hide the then unused config item but drop it completely by using a
dependency instead of a conditional prompt.
This fixes DEBUG_IMX_UART_PORT being present in the kernel config even
if DEBUG_LL is disabled.

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.
