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.

config SND_DESIGNWARE_I2S
	tristate "Synopsys I2S Device Driver"
	depends on HAVE_CLK
	select SND_SOC_GENERIC_DMAENGINE_PCM
	help
	 Say Y or M if you want to add support for I2S driver for
	 Synopsys designware I2S device. The device supports up to
	 a maximum of 8 channels each for play and record.

config SND_DESIGNWARE_PCM
	bool "PCM PIO extension for I2S driver"
	depends on SND_DESIGNWARE_I2S
	help
	 Say Y or N if you want to add a custom ALSA extension that registers
	 a PCM and uses PIO to transfer data.

	 This functionality is specially suited for I2S devices that don't have
	 DMA support.

Annotation

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.
