Subject: [PATCH 0/8] drm/solomon: Add support for the SSD132x controller family

Hello,

This patch-set adds support for the family of SSD132x Solomon controllers,
such as the SSD1322, SSD1325 and SSD1327 chips. These are used for 16 Gray
Scale Dot Matrix OLED panels.

The patches were tested on a Waveshare SSD1327 display using glmark2-drm,
fbcon, fbtests and the retroarch emulator.

Patch #1 renames the ssd130x driver to ssd13xx since it will support both
the SSD130x and SSD132x Solomon families and at least the SSD133x family
in the future.

Patch #2 also renames the data structures and functions prefixes with the
ssd13xx name.

Patch #3 drops the .page_height field from the device info with a constant
because it's only needed by the SSD130x family and not the SSD132x family.

Patch #4 changes the driver to use drm_format_info_min_pitch() instead of
open coding the same calculation.

Patch #5 adds a per controller family functions table to have logic that
could be shared by both SSD130x and SSD132x callbacks.

Patch #6 renames some SSD130X_* commands that are shared by both families
and patch #7 adds the support for the SSD132x controller family.

Finally patch #8 adds a DT binding schema for the SSD132x device nodes.

Best regards,
Javier
