This adds a new driver for the Samsung DB7430 DPI display controller as controlled over SPI. Right now the only panel product we know that is using this display controller is the LMS397KF04 but there may be more. This is the first regular panel driver making use of the MIPI DBI helper library. The DBI "device" portions can not be used because that code assumes the use of a single regulator and specific timings around the reset pulse that do not match the DB7430 datasheet.

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.
