Annotated Snippet
- compatible: "cavium,octeon-3860-twsi"
Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs.
or
compatible: "cavium,octeon-7890-twsi"
Compatibility with cn78XX SOCs.
- reg: The base address of the TWSI/I2C bus controller register bank.
- #address-cells: Must be <1>.
- #size-cells: Must be <0>. I2C addresses have no size component.
- interrupts: A single interrupt specifier.
- clock-frequency: The I2C bus clock rate in Hz.
Example:
twsi0: i2c@1180000001000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "cavium,octeon-3860-twsi";
reg = <0x11800 0x00001000 0x0 0x200>;
interrupts = <0 45>;
clock-frequency = <100000>;
rtc@68 {
compatible = "dallas,ds1337";
reg = <0x68>;
};
tmp@4c {
compatible = "ti,tmp421";
reg = <0x4c>;
};
};
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.
