Annotated Snippet
Generic devicetree bindings for onewire (w1) busses
===================================================
Onewire busses are described through nodes of their master bus controller.
Slave devices are listed as sub-nodes of such master devices. For now, only
one slave is allowed per bus master.
Example:
charger: charger {
compatible = "gpio-charger";
charger-type = "mains";
gpios = <&gpio 1 GPIO_ACTIVE_LOW>;
};
onewire {
compatible = "w1-gpio";
gpios = <&gpio 100 0>, <&gpio 101 0>;
battery {
compatible = "maxim,ds2760";
power-supplies = <&charger>;
};

- 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.
