The DP Port may attach a DP MST bridge device as follow: +-------------------------+ +---------------------------------+ | | | | | +---------+ | | +-------------+ | | | | | | | | | stream0 | | | | Output Port1| | | | | | | | | +---------+ | | +-------------+ | | | | | | | | | +---------+ | +-------------+ +-------------+ | | | | | | | | | DP Port | stream1 | +------> Input Port0 | | Output Port2| | | | | | | | | | +---------+ | +-------------+ +-------------+ | | | | | | | | | +---------+ | | +-------------+ | | | | | | | | | stream2 | | | | Output Port3| | | | | | | | | +---------+ | | +-------------+ | | | DP MST Bridge | +-------------------------+ +---------------------------------+ The DP MST bridge device may be a branch device, such as DP MST HUB, the branch unit in DP MST monitor, A DP MST bridge chip and so on. When a sink device connected to the DP MST bridege device's output port, The sink device may receive the stream from steram0/1/2. When the DP MST bridge device is a bridge chip and the output port attach to a fixed device(another bridge device or panel). The output port may want bind itself to a fixed stream. To satisfy this requirement, The prop "rockchip,mst-fixed-ports" is used to do it. For example, define as follow: rockchip,mst-fixed-ports = <1 2 3>; It mean that: DP Port stream0 --> DP MST bridge Output Port1 DP Port stream1 --> DP MST bridge Output Port2 DP Port stream2 --> DP MST bridge Output Port3 Change-Id: I91dfc51a5e8a533ebbabdcae572163907ec2c9fe Signed-off-by: Zhang Yubing <yubing.zhang@rock-chips.com>
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.
