[PATCH v5 0/4] drm/solomon: Add support for the SSD133x controller family

[Javier Martinez Canillas <javierm@redhat.com>]

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 v5 that is basically the same than the previous v4 but dropping
support for I2C since the ssd133x family does not support that interface.

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

Changes in v5:
- Drop I2C example in DT binding schema due that bus not being supported.
- Drop "solomon,ssd1331" entry from ssd130x-i2c due I2C bus not being supported.

Changes in v4:
- Fix typo in commit message (Jocelyn Falempe).
- Add collected tags.

Changes in v3:
- Move solomon,ssd-common.yaml ref before the properties section and
  width/height constraints after the other properties (Conor Dooley).

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