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.

	bool "SDCA IRQ support"
	select REGMAP
	select REGMAP_IRQ
	depends on SND_SOC_SDCA
	default y
	help
	  This option enables support for SDCA IRQs.

config SND_SOC_SDCA_FDL
	bool "SDCA FDL (File DownLoad) support"
	depends on SND_SOC_SDCA
	default y
	help
	  This option enables support for the File Download using UMP,
	  typically used for downloading firmware to devices.

Atlas domain: Driver Families / sound/soc.
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.
