[PATCH v4 01/10] dt-bindings: display: Add YAML schema for JH7110 display pipeline

Tue May 21 03:58:08 PDT 2024
JH7110 SoC display pipeline includes a display controller and hdmi.
Dc controller IP : Vivante DC8200 Dual Display
HDMI IP : INNOSILICON HDMI2.0
As the INNO hdmi ip is also used by rockchip SoC in the driver code,
the innosilicon,inno-hdmi.yaml schema containing the common properties
for the INNO DesignWare HDMI TX controller isn't a full device
tree binding specification, but is meant to be referenced by
platform-specific bindings for the IP core.

+description: |
+ This document defines device tree properties for the Innosilicon HDMI TX
+ controller (INNO HDMI) IP core. It doesn't constitute a full device tree
+ binding specification by itself but is meant to be referenced by device tree
+ bindings for the platform-specific integrations of the INNO HDMI.
+
+ When referenced from platform device tree bindings the properties defined in
+ this document are defined as follows. The platform device tree bindings are
+ responsible for defining whether each property is required or optional.
