possible_clones is used to indicate which other encoders can share
a CRTC with the current encoder. The default logic is that an encoder
can exclusively occupy one CRTC. However, in scenarios such as writeback
or connector mirroring, we can support multiple encoders sharing one
CRTC, hence this logic is introduced.
If less this commit, the writeback or connector mirror will commit
failed at the drm_atomic_check_valid_clones(), which is introduced by
the following commit:

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.
