Subject: [PATCH v2 0/2] drm/solomon: Add support for the SSD133x controller family

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 v2 that addresses issues pointed out in v1:

https://lore.kernel.org/lkml/20231217100741.1943932-2-javierm@redhat.com/T/

The patches were tested on a Waveshare SSD1331 display using glmark2-drm,
fbcon, fbtests and the retroarch emulator.

Patch #1 adds a DT binding schema for the SSD133x controllers and patch #2
extends the ssd130x DRM driver to support the SSD133x controller family.

Best regards,
Javier

Changes in v2:
- Unconditionally set the width and height constraints (Conor Dooley).
- Fix indentation in the DTS examples (Krzysztof Kozlowski).
