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.

	  cx231xx hardware has a builtin RX/TX support. However, a few
	  designs opted to not use it, but, instead, some other hardware.
	  This module enables the usage of those other hardware, like the
	  ones used with ISDB-T boards.

	  On most cases, all you need for IR is mceusb module.
