Hello,

This patch-set adds support for the family of SSD133x Solomon controllers,
such as the SSD1331. These are used for RGB Dot Matrix OLED/PLED panels.

This is a v4 that addresses issues pointed out in v3:

https://lists.freedesktop.org/archives/dri-devel/2023-December/435686.html

The patches were tested on a Waveshare SSD1331 display using glmark2-drm,
fbcon, fbtests and the retroarch emulator. The binding schema were tested
using the `make W=1 dt_binding_check` target.

Patch #1 and #2 are fixes for the DT binding schema of the existing SSD130x
and SSD132x families.

Patch #3 adds a DT binding schema for the SSD133x controllers and patch #4
extends the ssd130x DRM driver to support the SSD133x controller family.

Best regards,
Javier
