Annotated Snippet

Texas Instruments OMAP4 Display Subsystem
=========================================

See Documentation/devicetree/bindings/display/ti/ti,omap-dss.txt for generic
description about OMAP Display Subsystem bindings.

DSS Core
--------

Required properties:
- compatible: "ti,omap4-dss"
- reg: address and length of the register space
- ti,hwmods: "dss_core"
- clocks: handle to fclk
- clock-names: "fck"

Required nodes:
- DISPC

Optional nodes:
- DSS Submodules: RFBI, VENC, DSI, HDMI
- Video port for DPI output

DPI Endpoint required properties:

Optional nodes:

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
