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.

	  Add some dummy events to the simple dummy driver.

	  The purpose of this is to generate 'fake' event interrupts thus
	  allowing that driver's code to be as close as possible to that
	  a normal driver talking to hardware.

	bool "Buffered capture support"

	  Add buffered data capture to the simple dummy driver.

	  Buffer handling elements of industrial I/O reference driver.
	  Uses the kfifo buffer.
