Fixes: d420d65bec ("drm/rockchip: dsi2: optimize drive probe process")
rockchip drm will Registers a new aggregate driver consisting of the
components added to @match by calling one of the component_match_add()
functions. Once all components in @match are available, it will be assembled
by calling &component_master_ops.bind(rockchip_drm_ops.rockchip_drm_bind)
from @ops.
if the dsi->slave is not added into component, the binding status of
the device under the display subsystem becomes abnormal as follows:
cat /sys/kernel/debug/device_component/display-subsystem
aggregate_device name status
-------------------------------------------------------------
display-subsystem not bound
device name status
-------------------------------------------------------------
fdd90000.vop not bound
fde20000.dsi not bound
(unknown) not registered

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.
