This patch replaces ->mode_fixup() with ->atomic_check() so that a full modeset can be requested from there when crtc_state->active is changed to be true(which implies only connector's DPMS is brought out of "Off" status, though not necessarily). Bridge functions are added or changed to accommodate the ->atomic_check() callback. That full modeset is needed by the up-coming patch which gets MIPI DSI controller and PHY ready in ->mode_set(), because it makes sure ->mode_set() and ->atomic_disable() are called in pairs.

README
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.
