Subject: [PATCH v5 1/9] dt-bindings: display: bindings for starfive,JH7110 display pipeline
- Added bindings to support the display subsystem on the JH7110 SoC.
- Included the DC8200 display controller and Inno HDMI controller.
- Created innosilicon,inno-hdmi.yaml schema containing common properties
for the Inno DesignWare HDMI TX controller.
This isn't a full device tree binding specification,
but is intended to be referenced by platform-specific bindings
for the IP core.

+title: Starfive JH7110 SoC Display Controller (DC8200)
+
+description:
+ The STARFIVE JH7110 SoC uses the display controller based on Verisilicon
+ IP(DC8200) to transfer the image data from a video memory buffer to an
+ external LCD interface.
+
+ pipe0 binds HDMI for primary display,
+ pipe1 binds DSI for external display.
