[PATCH v2 5/6] dt-bindings: display: Split common Solomon properties in their own schema

From: Javier Martinez Canillas
Date: Thu Oct 12 2023 - 02:59:59 EST


There are DT properties that can be shared across different Solomon OLED
Display Controller families. Split them into a separate common schema to
avoid these properties to be duplicated in different DT bindings schemas.
