Annotated Snippet

Wondermedia WM8505 Framebuffer
-----------------------------------------------------

Required properties:
- compatible : "wm,wm8505-fb"
- reg : Should contain 1 register ranges(address and length)
- bits-per-pixel : bit depth of framebuffer (16 or 32)

Required subnodes:
- display-timings: see display-timing.txt for information

Example:

	fb@d8051700 {
		compatible = "wm,wm8505-fb";
		reg = <0xd8051700 0x200>;
		bits-per-pixel = <16>;

		display-timings {
			native-mode = <&timing0>;
			timing0: 800x480 {
				clock-frequency = <0>; /* unused but required */
				hactive = <800>;
				vactive = <480>;
				hfront-porch = <40>;
				hback-porch = <88>;
				hsync-len = <0>;
				vback-porch = <32>;
				vfront-porch = <11>;
				vsync-len = <1>;
			};
		};
	};

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.
