	  Enable this to support the Intel Burnside Bridge Thunderbolt / USB /
	  DisplayPort retimer.

	  Intel Burnside Bridge is a Type-C multi-protocol retimer to be used
	  in on-board applications. Burnside Bridge offers the ability to latch
	  protocol signals into on-chip memory before retransmitting them
	  onwards. It can be used to extend the physical length of the system
	  without increasing high-frequency jitter.

	  Burnside Bridge supports spec compliant retimer of following
	  protocols:

	    - Display Port: four unidirectional DP lanes
	    - USB3.1 Gen1/2: one bi-directional USB lane
	    - Thunderbolt: two bi-directional CIO lanes
	    - Multifunction Display (MFD): two unidirectional lanes of DP and
	      one bidirectional lane of USB3.1 Gen1/2

	default y
	help
	  Enable this to allow run-time configuration of the Burnside Bridge
	  driver structure. This makes the bb_controls[] array writable, i.e.
	  not const. It should be declared as such in the board config.

	  This is useful when the board has runtime information that changes
	  the configuration, such as Chromium OS Board Info (CBI set in the
	  factory. Without this, multiple EC images would need to be installed
	  depending on the board.

	help
	  ANX7451 is a 4x4 re-timing mux capable of switching DisplayPort (DP)
	  and USB3.2 Gen 2 10Gbps signals to support a single USB Type-C port.
	  ANX7451 has built-in re-timers to recover both the USB and DP signals
