The RG28XX panel is a display panel of the Anbernic RG28XX, a handheld gaming device from Anbernic. It is 2.8 inches in size (diagonally) with a resolution of 480x640. This panel is driven by a variant of the ST7701 driver IC internally, confirmed by dumping and analyzing its BSP initialization sequence by using a logic analyzer. It is very similar to the existing densitron,dmt028vghmcmi-1a panel, but differs in some unknown register values, so add a new entry for the panel to distinguish them. Additionally, the panel only has an SPI instead of MIPI DSI. So add and modify for SPI as well. Although a panel connected via SPI with a D/CX pin theoretically exists, no such panels have been found for this driver yet. Therefore, disable the use of the dc-gpios property for all currently known devices.

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 reStructuredText 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.
