Annotated Snippet

Sony CXD2880 DVB-T2/T tuner + demodulator driver SPI adapter

Required properties:
- compatible: Should be "sony,cxd2880".
- reg: SPI chip select number for the device.
- spi-max-frequency: Maximum bus speed, should be set to <55000000> (55MHz).

Optional properties:
- vcc-supply: Optional phandle to the vcc regulator to power the adapter,
  as described in the file ../regulator/regulator.txt

Example:

cxd2880@0 {
	compatible = "sony,cxd2880";
	reg = <0>; /* CE0 */
	spi-max-frequency = <55000000>; /* 55MHz */
};

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.
