Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• enum cx18_gpio_reset_type

Annotated Snippet

void cx18_gpio_init(struct cx18 *cx);
int cx18_gpio_register(struct cx18 *cx, u32 hw);

enum cx18_gpio_reset_type {
	CX18_GPIO_RESET_I2C     = 0,
	CX18_GPIO_RESET_Z8F0811 = 1,
	CX18_GPIO_RESET_XC2028  = 2,
};

int cx18_reset_tuner_gpio(void *dev, int component, int cmd, int value);

Annotation

• Detected declarations: `enum cx18_gpio_reset_type`.
• Atlas domain: Driver Families / drivers/media.
• Implementation status: source implementation candidate.

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.
