Annotated Snippet

Texas Instruments DRA7x 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,dra7-dss"
- reg: address and length of the register spaces for 'dss'
- ti,hwmods: "dss_core"
- clocks: handle to fclk
- clock-names: "fck"
- syscon: phandle to control module core syscon node

Optional properties:

Some DRA7xx SoCs have one dedicated video PLL, some have two. These properties
can be used to describe the video PLLs:

- reg: address and length of the register spaces for 'pll1_clkctrl',
  'pll1', 'pll2_clkctrl', 'pll2'
- clocks: handle to video1 pll clock and video2 pll clock
- clock-names: "video1_clk" and "video2_clk"

Required nodes:
- DISPC

Optional nodes:
- DSS Submodules: HDMI
- Video port for DPI output

DPI Endpoint required properties:
- data-lines: number of lines used


DISPC
-----

Required properties:
- compatible: "ti,dra7-dispc"
- reg: address and length of the register space
- ti,hwmods: "dss_dispc"
- interrupts: the DISPC interrupt
- clocks: handle to fclk
- clock-names: "fck"

Optional properties:
- max-memory-bandwidth: Input memory (from main memory to dispc) bandwidth limit
			in bytes per second


HDMI
----

Required properties:
- compatible: "ti,dra7-hdmi"
- reg: addresses and lengths of the register spaces for 'wp', 'pll', 'phy',
       'core'
- reg-names: "wp", "pll", "phy", "core"
- interrupts: the HDMI interrupt line
- ti,hwmods: "dss_hdmi"
- vdda-supply: vdda power supply
- clocks: handles to fclk and pll clock
- clock-names: "fck", "sys_clk"

Optional nodes:
- Video port for HDMI output

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.
