[PATCH v2 0/6] drm/solomon: Add support for the SSD132x controller family

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

This is a v2 that address issues pointed out during review of the v1:

https://lists.freedesktop.org/archives/dri-devel/2023-October/426039.html

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

Patch #1 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 #2 adds a per controller family functions table to have logic that
could be shared by both SSD130x and SSD132x callbacks.

Patch #3 renames some SSD130X_* commands that are shared by both families.

Patch #4 adds the support for the SSD132x controller family.

Patch #5 splits out some properties that are shared across both controller
families bindings and move them into a separate solomon,ssd-common schema.

Finally patch #6 adds a DT binding schema for the SSD132x controllers.

Best regards,
Javier

Changes in v2:
- Add Geert Uytterhoeven's Reviewed-by tag to patch #1.
- Squash patch that uses drm_format_info_min_pitch() to calculate dest_pitch
  with the following patch (Geert Uytterhoeven).
- Store ssd13xx_family_funcs[SSD130X_FAMILY] in struct ssd130x_deviceinfo
  (Geert Uytterhoeven).
- Don't mix switch (family_id) and ssd13xx_funcs[family_id] (Geert Uytterhoeven).
- Replace switch (family_id) by an .set_buffer_sizes (Geert Uytterhoeven).
- Move the rect alignment to a per chip family function (Geert Uytterhoeven).
- Align the rectangle to the segment width (Geert Uytterhoeven).
- Drop patches that rename driver and prefixes (Maxime Ripard, Peter Robinson).
- Remove unnecessary 'oneOf' in the SSD132x DT binding schema (Conor Dooley).
- Remove unused DT nodes labels in the binding schema examples (Conor Dooley).
- Split out common Solomon properties into a separate schema (Rob Herring).
