Subject: [PATCH v2 6/6] dt-bindings: display: Add SSD132x OLED controllers
Add a Device Tree binding schema for the OLED panels based on the Solomon
SSD132x family of controllers.
Signed-off-by: Javier Martinez Canillas <javierm@...hat.com>
---
Changes in v2:
- 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).
