This panel can be accessed using both SPI and DSI. To make it possible to probe and use the device also from a DSI bus, first break out the SPI support to its own file. Since all the panel driver does is write DCS commands to the panel, we pass a DCS write function to probe() from each subdriver. We make the Kconfig entry for SPI mode default so all current users will continue to work.

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.
