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.

	  The kernel has 2 drivers for the Low Power Engine audio-block on
	  Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF
	  driver. If both drivers are enabled then the kernel will default
	  to using the old SST driver, unless told otherwise through the
	  snd_intel_dspcfg.dsp_driver module-parameter.

	  Set this option to Y to make the kernel default to the new SOF
	  driver instead.
