When we enable Dual LVDS, there will be the following
output in the VOP summary node:
$ cat /sys/kernel/debug/dri/0/summary
...
Video Port1: ACTIVE
Connector: LVDS-1
...
The connector information here is not clear enough. When Dual LVDS is enabled,
both LVDS-0 and LVDS-1 will be enabled (but we will only expose one connector
to user space for operation, which can shield the underlying differences).
In addition, if only LVDS1 is enabled instead of using Dual LVDS,
"LVDS-1" will also be printed here.
In order to express this information more accurately, we will change
the corresponding connector name to "LVDS-DUAL" when using Dual LVDS:
$ cat /sys/kernel/debug/dri/0/summary
...
Video Port1: ACTIVE
Connector: LVDS-DUAL
...

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.
