AngeloGioacchino Del Regno 3ca272b231 drm/mediatek: dsi: Add atomic {destroy,duplicate}_state, reset callbacks
[ Upstream commit eeda05b5e9 ]

Add callbacks for atomic_destroy_state, atomic_duplicate_state and
atomic_reset to restore functionality of the DSI driver: this solves
vblank timeouts when another bridge is present in the chain.

Tested bridge chain: DSI <=> ANX7625 => aux-bus panel

Fixes: 7f6335c6a2 ("drm/mediatek: Modify dsi funcs to atomic operations")

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.
