This patch adds a drm bridge driver for i.MX8qm LVDS display bridge(LDB) which is officially named as pixel mapper. The LDB has two channels. Each of them supports up to 30bpp parallel input color format and can map the input to VESA or JEIDA standards. The two channels can be used simultaneously, either in dual mode or split mode. In dual mode, the two channels output identical data. In split mode, channel0 outputs odd pixels and channel1 outputs even pixels. This patch supports the LDB single mode and split mode.

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.
