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.

	  This enables support for the MediaTek MT7530 and MT7531 Ethernet
	  switch chips. Multi-chip module MT7530 in MT7621AT, MT7621DAT,
	  MT7621ST and MT7623AI SoCs, and built-in switch in MT7988 SoC are
	  supported as well.

	  This enables support for the MediaTek MT7530 and MT7531 switch
	  chips which are connected via MDIO, as well as multi-chip
	  module MT7530 which can be found in the MT7621AT, MT7621DAT,

	help
	  This enables support for the built-in Ethernet switch found
	  in the MediaTek MT7988 SoC.
	  The switch is a similar design as MT7531, but the switch registers
	  are directly mapped into the SoCs register space rather than being
	  accessible via MDIO.
