Annotated Snippet

SMSC USB4604 High-Speed Hub Controller

Required properties:
- compatible: Should be "smsc,usb4604"

Optional properties:
- reg: Specifies the i2c slave address, it is required and should be 0x2d
       if I2C is used.
- reset-gpios: Should specify GPIO for reset.
- initial-mode: Should specify initial mode.
                (1 for HUB mode, 2 for STANDBY mode)

Examples:
	usb-hub@2d {
		compatible = "smsc,usb4604";
		reg = <0x2d>;
		reset-gpios = <&gpx3 5 1>;
		initial-mode = <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.
